That’s a great mindset when you’re doing it for you. I run less fun trail runs and more competitive track races so I use apps like strava and Garmin to make sure I’m training at the paces and speeds that I need to in order to do well in my races and it payed off. I placed 3rd in a 1600 yesterday with a huge PR and it was really difficult but I trained for it and it worked out. Running and similar things are different for everyone. Even if you do want to win races, many races (like the western states endurance race) are won at 9:00/mi (5:35/km)! Personally, I have the most fun running with my friends so I do my fast speed days and my slow recovery days with friends whenever I can. If you have fun just enjoying your surroundings and taking it easy- that’s awesome too!

Ive started hiking training. 5 days a week i walk in the morning, on breaks, and after work. Thats 2-4 miles a day. Just teaching my body to get use to move. On the weekends I do one hard day slowly increasing my max mileage. Last week I did 6.3 miles in one day. This weekend is 6.5. The day after is a rest day. It works for me.

That sounds like a good plan.

Aerobic base building doesn't have to suck. Audiobooks on trails, chug along at a low-ish heart rate (aka "I could run at this pace forever"). It's absolute heaven. It feels like a treat, not a chore.

I’m 55, an avid weekend day hiker, lift with a trainer during the week. I’m healthy and in great shape. I’m going to be doing Rim 2 Rim at the Grand Canyon in May of 2023 and I know I have to train differently so as not to blow my knees out ( replaced ACL in R knee ). You were automatically my go-to for solid information on training and stretching and I’m not disappointed!

Well said. At 61, Maffetone taught me that real aerobic fitness comes from being able to do it again without being injured! It's a lot more engaging and fun.

Yeah when you're in the mountains, you want to be fit enough for a LONG detour. Had to do that recently and it was scary, because some in our group weren't used to excerting themselves for long.

Undoubtedly the best video I've seen for aerobic training. The principles are so simple and so basic that, without having experienced them, they could be easily dismissed as too basic and not challenging enough to provide significant gains. Don't be dissuaded; you will start WAY slower than you think you should, but stick with it. You will recover faster, your injury risk will plummet and you will find that your body will be a able to move farther and faster at the lower heart rate. An extra added benefit; you will gradually train your body to rely more heavily on its fat stores for fuel than on its limited stores of carbohydrate, which will enable you to go longer with less fatigue. Combine these principles with a sensible strength training program and you will be amazed at what your body is capable of. I've done multiple Ironmans as well as marathons, trail runs and long distance hikes using these principles and there's no question in my mind that, especially for non-elite athletes, this is the way to go. Many thanks, Chase, for this great video!

Such a great video. I really appreciate the clear, strong messaging.

Clear message and so true. Highly recommended and clearly one of my favourite KZread videos! Thank you!

Very good points. The key takeaway is that everyone is different, and you need to pay attention to your own body. I also think that diet is the most important foundation of any fitness program. After leaving Microsoft 10 years ago, I changed my diet to cutout the junk and focus on fruits, vegetables, and lean proteins. Over the following year, I lost 30 lbs, and ran my first 50k ultra. A lot of other friends have had similar experiences. A friend of mine gave up alcohol and lost 20 lbs in 2 months! Diet is everything.

Great points! I always catch myself going too hard during easy aerobic sessions, it's not always supposed to be hard!

As usual, very informative video! Love your work💪⛰

Some seriously great nuggets in there! Brilliant

That was some rock solid advice. I've had so many injuries from not being able to cut down on the ego and train slowly

Mind = blown! Such helpful information. Thanks Chase!

Amazing advice 46 years of age and only just learned this for myself! Save years and take this on board now

I loved listening to your video. Some of your words even got me a bit emotional because of the loving undertone and you really gave a reality check. Thank you for this! I just got into training more before going on long hikes and loving the journey so far...

Absolutely awesome advice ..I 'know ' this but still fall down the rabbit hole of not carrying on with it long term and ramping either volume or speed up. Then an injury follows..always. Thanks for the reminder x

I didn't understand much of what you said, but I can read. Always enjoy listening to you trying to help me.

I’ve always found the key to training and prepping for big projects is conditioning. Having that base and consistency helps your endurance, and most importantly, prevents injury. I typically average 20-25 miles on a hike and I can honestly say I would have never reached that without the months of hiking I did prior

Thanks, Chase. Super helpful and informative as always.

What a fantastic video. As a long time hiker/ climber, I transitioned to ultra running last year- doing what I was already doing, but faster and with a lighter pack. Trying to build my cardio system has been more difficult than I expected, mostly due to ego, but this video was full of great info to help!

Great Video, Great message. Thanks for this.

Great video and channel Chase. The most gains I ever made when it came to hiking speed and how I felt overall during a hike/camping trip came from when I would do long, slow hours of cardio almost every day of the week. I'd average maybe only 2 hours of walking/jogging a day and the overall improvement to my healthy was ridiculous.

Brilliant advice! You're an inspiration man

I am an athlete, i coach athletes and I could not agree more! Love it

This is such a great video. Thank you! I am 59, closer to 60, and using this exact approach for training to summit Mont Blanc in June ‘24. This weekend I hiked 6 x hills (up and down) totalling 577m vertical in 1h 26m. And I didn’t break a sweat. My aim is to add a weighted bag (incrementally to max 10kg) and achieve 10 of the same hills to 1,000m vertical before I go. Endurance training works.

I used to be one of those who do too much, too fast, and end up discouraged and injured. Your programme is a great lesson in pacing (and humility!). Also, I have spent the last 35 years with a nagging back injury, and the single one thing that helped was doing your Daily Move. I'm on day 12, and it's already made a difference. I think it's the hip mobility that's helping the most. Thank you so much for everything you do!

Very agreeable video. I concur that the phrase "fitness" is an ethereal concept and that health and wellbeing + repetitive consistant practice are synergy that creates the ability.

That's a very good mindset and i think that the satisfaction you get of being able to run for such distances makes you keep going and enjoy it even more

Excellent advice. Thank you!

What is real is to stop talking and find every excuse not to do.Excellent video tx for sharing

Thank you for bringing up progressing with out adding stress. That is the one thing I struggle with is stress when adding any workout. I progress and build in endurance very quickly but to a fault that it can add LOTS of stress abd I end up quitting.

Great tips to remember Chase

Thankyou for this...you've echod my heart cardiologist. Im in rehabilitation phase and suffering from dizziness,etc when out walking...he simply said if you can't hold a conversation you're doing to much.

finally understanding the importance of going slow to go fast... 2 years after you posted this. I didn't have an issue with hiking because I must have had a good hiking aerobic base, but as soon as I started mountain biking last year I started burning out FAST. I was pushing into zones 4-5 way too much and not realizing I needed a biking aerobic base. But it's really difficult to stay at zone 2 in the mountains here with biking, so I'm not sure what to do...

Awesome insights. Thanks

That was a great video, thank you!

Exactly, when I train for Mt Whitney Ca 2019, I did my research. I hiked long distance with high altitude with my club or solo, stair training, long walks as well as backpacking training. Summit Mt Whitney 2019 👍 with my hiking friends. All my training paid off.

Great Info 💪

Great tips that both match to and inspire my intermediate experience level (couple of half marathons) Thanks for the book recommendation - definitely want to add that to my running library!!

Great advice here

Just found you today. I always think about all the cool outdoor things I want to do, but I'm also not fit. scratch that. healthy. I need to work on me a little more instead of just buying cool stuff to be ready to go outside without training first. I definitely appreciate hearing that is not all about catching that Max heart rate or zippy treadmill time, but just to go for the longer endurance times, and be consistent with it. I think I'm going to learn a lot from your channel. Thanks.

Thanks for this, I believe I learned something.

Great advice.🤘😎

Man, great content that needs more visibility! Really appreciate your approach….

Mobility, putting in the daily, weekly. Focus zone training, Zone 1-2 . Recovery days , I raced bikes when i was close 30. Looking back I overtrained. Walking fast with heart monitor was start. I did my homework .

For me hiking turned out to be the exact exercise I needed to get in shape when I was younger. And it was the hiking itself, it wasn't anything else. I did some other stuff too (mostly martial arts) which was great for endurance training... but what really got me into shape was doing the same hike near my house over and over and over until I started expanding further and further into that park, and was able to run up hills I could barely hike up before. It's been a while since I've done any real hiking, and I really just need to bite the bullet and do it now that quarantine is loosening and vaccines are available. Like you're saying about "heart rate zones," throw out all those armchair theories about how to hike and just hike. "Nothing of any real value can be taught." Amen. Learn by doing, especially when it comes to physical endeavors like hiking.

Great advices! I wanted to do an 800km hike within 21 days this year but 'thanks' to the pandemic I won't. And that's good because I was definitely not ready to do it in this timeframe. Which gives me more time to slowly and consistently prepare for this goal. One more comment I would add (but it's more about safety rather than training) is to always respect the mountain. And I don't mean it in a hippy way. I mean respect nature and how powerful the elements are and always, always remember to judge your abilities and conditions on the trail carefully. This is especially important in these times where thanks to Instagram (or any other social media for that matter) 'influencers', disconnect from reality is just getting bigger and bigger.

I really really enjoy your videos and tips. I am 23 years old and going to climb Kili in June. I have no prior experience climbing a mountain to this level. I’m really interested in purchasing your 5 week training program to help me get started. I have asthma and I need to build my cardiovascular strength so I don’t end up gasping for air on the climb. Thanks for all of your great advice!

Good advice mate. I had to learn it the hard way and it left scars😕.

I tried MAF training a twice when I was in my 40s. Once for 18 months and once for 9 months. But I didn't adjust my diet to his principles at the time and I really think that hindered my progress. I was eating the usual tons of power bars (various brands) and surgery drinks and gels. I was able to go very long, but always painfully slow. Now, in my 60s, I'm taking another shot at MAF. It's nice to see that he's become more active in the last few years. Nice motivational video too! I'm glad KZread recommended you!

This is excellent, and accurate

Any advice is better than no advice at all.

Not that I am an expert, but I do have 40 years of making mistakes. :) I now do something very much aligned with these ideas. I have no genetic gifts, born weak and slow. Using these ideas I can grind out a 20 hour push above 20,000 ft, no problem, day after a push to get to high camp. I used a more HIT-centric approach for a while back about age 50 and had slipped so a 10 mile 4,000 ft gain day at low altitude was a very full day; thought it was just age until I revamped my training along these lines. After 9 months of using these ideas did a 22 mile, 9,000 vertical foot day to celebrate turning 60 smiling the whole time, very moderate day, and a few months later a 1,000 ft WI5 ice climb. This works. I would say you do not need a heart monitor. Out on the trail, just slow enough to put your hand on your throat to feel your pulse. Count for 15 seconds and multiply by 4. Easiest to count to 25 (x4 = 100), and then start again, x4 and add. So say you count to 25, then count to 12. Pulse is 148. Pay attention to how you feel and how you are breathing. Very soon you can tell your heart rate very closely without needing to measure. Now if you find a HR monitor, downloading to your computer is fun or motivational, that is 100% fine, whatever works for you. I strongly suggest not guessing your max heart rate by using a formula if you are going to use a HR based method. People are far too variable. If you are healthy, measure it directly. Run hills, crank a treadmill to max incline, use a stairmaster, and push very hard. My max HR at age 60 was 190. (In explaining this to my wife she told me to stop doing that, and given my age I decide maybe she was right. So you young bucks, measure, don't guess). That said, frankly the "conversation" threshold is likely just as good. Make sure you have enough rest days. You need rest to get benefit from training! Anyway, sorry for carrying on. I have made lots of mistakes over the years. Had my share of over training injuries. But this advice works!

Great video, the frustration is real especially if you are over 50 that MAF formula makes you feel embarrassed about the pace you are going - but with consistency (every day), focus (dedicating a long time per day to train), and with eating and drinking proper foods the results do not come immediately but long term you become a more resilient and relish your training as your aim is not to hurt yourself every time you go out. I still want to be hiking when I am 85 and beating the crap out of my body every time I train just reduces the longevity of my ability to do what I love ❤️

I totally agree with you! I'm 55, have started a focused MAF effort over the past 3 months and am definitely feeling the benefits. It was indeed embarrassingly slow at the beginning, but I can see the pace at the same heart picking up a bit already. This stuff works, and onward to age 85! 👍

It's unfortunate to have to play into the click-baity sounding video titles but I'm glad I watched this. I really like your approach and philosophy on fitness/health. Very inspiring!

Thank you for the upload bud. Just one thing I want to highlight: that working at different cadences means changes in stride length & total body movement; even when using a fixed position apparatus such as a bicycle, will automatically make you change body position & seat position so you use a different muscle preferentially over another. So the take home message is: do not try to run slow like you would run fast & visa versa. There are some most excellent KZread videos on running form by the Kenyan team & TEAM GB :::)). Stay strong: stay motivated; stay disciplined, stay safe!!!

Finally, someone who preaches wisdom in health rather than ignorance in fitness. I spend hours of my work week trying to rectify the damage caused by the 'no pain, no gain' brigade. Thanks Chase for your words of wisdom🙏

I did running, cycling and combination. But the best advice is just hike, hike, hike...with a pack. Built it up slowly...

Word up ! I get up 2x a week even if it's just for a few hrs! God bless training 🙏

When go to the trails I go a pace I can keep and dont worry about walking phases. As a result i end up running over an hour without realising it, whereas 30 min of roadrunning is just sooo long lasting. Time freezes. Trails on the other hand is just magical.

I was always trying to figure out how to fit more trail running into my schedule without being too exhausted for work, but doing a couple slow tail hikes during the week will work. Thank you for the advice. How to keep from turning it into a trail run? Not wearing my running shoes.

This was something I wish I realized sooner. I was also searching for a P90X or Insanity or CrossFit or powerlifting and was just googling pros and cons and never really sticking to something. It just resulting in me training for a few weeks then back to the couch. It wasn’t until I just started something very simple. Walking for an hour every day, rain or shine, doesn’t matter. Just walk. That walk turned into adding C25K. 4 months later I was running 5K three times a week. Then trained for a 10K. Then got into calisthenics. All from building a very simple habit. Walking.

I started running in zone 2 for 90% of my runs and slowly but surely in 2months I'm starting to see the results, getting less tired, heart rate on easy runs stays well below my age threshold and recently had my PB in a 10K race. I only do 1 or 2 speed session per week.

@@tritondriver1 You think you would have been able to run long Ultras without training hard?

I have found that the training I needed for competitive conditioning and what I need for health and enjoying hiking are entirely different. If I tried the exercise I did as a college 800 meter runner, even age adjusted to account for the 42 years that have gone by since then, I'd ruin my health and be constantly injured, rather than improve my health. I thought the 180 formula was for wimps. Now it's most of my workouts.

5:50 same concept of my preferred strength program, (a mix of 5-3-1 with some added peripheral things). Always try to work at 90% not 100%. It's quite hard as ego gets in the way and you often want to attempt to set a new pr. While instead that would be just once per month at maximum. Not the fastest routine for competitions, but a good method (for me) that has reduced my overall pains/injuries substantially. Every month, if you manage to go over your set 90% with a certain ease, then you may increase at maximum 5kgs on legs and 2.5k on upper body, IF you are eating in slight surplus or at least maintaining with an adequate diet. I have found (for me) the most effective for overall lung capacity to be a 4by4 (to be done once a week, not more. or, at least 3 days break from this or any other straining cardio exercise, game, match, etc. so if you have a game or match or hike on saturday, i would not do a 4by4 after wednesday.) Obviously requires that you have already a decent training, such that pushing with such intensity does not represent a risk of injury. I use ellipsis as i do not want to overstress my knee with more running. Preferably done with a partner, or hard to push max. 10min warmup / 4min close to your limit - 2 min back to warmup pace - repeat 4 times. - 10 minutes warmup pace at end. It's quite hellish, 4 min is more than you might think. After a couple months the difference is quite noticeable, in all the other sports i do. That's the case with any cardio exercise, but i've felt particular efficiency with this one. Maybe also works specifically well in combination with the rest of what i do (move only by bike, sold car last year, spar twice a week, in mountains on weekly basis, 3-4 days strength / week). Not an optimal combination of sports, but i enjoy them. If i have any other heavy session of other sport, then i may skip 4by4 that week. *source of 4by4: my nutritionist in oslo, it is backed by an extensive study where they test how long you can hold your breath/pace before/after several X sessions of different types of rythms/patterns. This one was strikingly more efficient, i guess it works sort of like doing a 4min rep x 4 times in a similar way as you would train a strength muscle to become stronger and/or bigger? Since the heart is a muscle also?

This sounds logical and right . I am training for 18000 feet trek in November (-15 degree expected) my bmi is 20.5. I currently climb 🧗‍♀️ 30 floors with 7 kg backpack and 3 kms brisk walk. Also added yoga 5 days a week. (Lots of full body stretching and breathing exercises). What more can I add to my 7 day schedule. I can jog slowly continuously for only 500 meters. But without much weight on me.
