Just increase your cadence by shortening your strides, you can actually run very slowly, to keep that HR low enough. I run in minimalist sandals/vibram 5f so I'm forced to do that, but you can probably do that in any running shoes.

I'm a pretty muscular, beefy guy. Broke my ribs a little over a year ago, then got covid. I also cannot jog or run without my heart rate going way above zone 2. This had led me to the treadmill using the incline at low percentages. It allows me to perfectly adjust and maintain my target heart rate zones. The only downside is I don't get the sunshine lol.
@marc5279Ай бұрын
why do you play with guessing one's max heart rate when you can just look at it doing a hard high intensity intervals session? This is the thing: the more numbers you guess, the less accuracy you'll have in calculating HR zones. So, if you can objectively know your maxHR and rest heart rate (and thus heart rate reserve, which is maxHR-RHR), use both 2 to calculate HR zones and you'll probably hit a better guessing than if you were only calculating them by just using your rest heart rate and a theoreticall maxHR based on whatever this formula is doing. Know your rest heart rate (RHR), know your maxHR, and use this: RHR+(X%(maxHR-RHR)), where "X" is the percentage you want to know

So far i'm forced to do interval training: run 7 minutes and walk 1 minute for 1h and 1/2. I can run five times a week without feeling tired or sored. It's simply amazing the results you can get with this "simple" method.

I’ve recently returned to running after a long layoff due to health issues. I started with a basic walk/run method based on time - run for one minute, walk for one minute, etc. - and I was getting faster and running longer. Since I discovered the Maffetone and zone 2 training methods, I have had to slow down and walk a lot more than I was, and it feels like I’m going backwards.

If you want to try what you are referring to as Zone 2, the best way to do it is slow jogging where you take _very_ short steps, and that will keep you under. At this point (I'm mainly running to lose weight for now), I can stay in the slow jogging range with 11 minute miles. When I started, it took 14 or so. However, the ultimate goal is getting to Lydiard training this summer when I get back to something closer to racing weight.

Some people vary greatly from the age formula. Hal Higdon has one that is about 25 lower than suggested. If he tried to MAF at the age of 40 with his training, it would tell him to get to 145... when he had a maximum heart rate of 155 at the time, so MAF would have put him at 93.5% of his max, or almost certainly over his anaerobic threshold. Instead of going by any age formula, it's far better to try to figure out what their talking about and use a field test to figure out your max. MAF seems to be suggesting 80% maximum heart rate.

Man, this video feels like it validated like 5 different conclusions I've been coming to today. 1. A few weeks back, I came down with SI joint pain that shelves running until further notice (usually 20-30 miles a week). 2. After trying every stretch under the sun, I discovered glute bridges and donkey kicks provided the most immediate relief. 3. During a glute bridge, I noticed that the glute on the affected side wasn't firing nearly as much as the non-painful side. 4. Researching a bit more about what's going on, I learned about the balanced relationship between the glutes and hip flexors. 5. I realized how laser-tight my hip flexors were, and how that probably meant quads were doing work meant for that glute. 6. Though I still have SI joint irritation (that just needs to heal, ain't no miracle pop is going to fix that), I realize that the key is (a) lengthening the hip flexors with regular long stretches and (b) re-switching on the glutes with regular, long glute bridges and training myself to counter the anterior pelvic tilt that is switching that glute off AND shortening the hip flexor. How's my aim? Do I sound like a crazy person yet? 😆

When walking, they stick their leg out in front of their body and fall onto their heel - rinse and repeat. When jogging slowly they do the same and then when running they also do the same except that their higher speed has them airborne.
