Question 1: What would be a reasonable testing protocol for this? Some viewers have expressed doubts about the safety of this system particularly over an extended period of time and use by person heavier than yours truly. I typically do weighted pull ups 3-4 times a week with a single 45lbs plate. How should we test capacity beyond that? my max for weighted pull ups is around 90lbs in addition to my 170 lbs of bodyweight. A static load test is easy to perform but doesn't perfectly represent the dynamic load of a pull up. That doesn't mean a static load test has no informational value though so what static load weight would make you confident? Another way might be to load it with 250lbs of weights on stretch bands and then make a device that adds and subtracts an additional 20lbs to mimic a dynamic load. Question 2: what features would you like to see in a work out bench made out of the same materials?

I’m certain you’re correct that the plywood itself isn’t going to break. However, the true strength of a French cleat lies when the force is applied downwards, parallel to the wall surface. Because you’ve added a pretty decent lever with the pull-up bar, you’re probably applying a lot of force perpendicular to the wall and that’s not a particularly strong direction. More so testing if your construction will delaminate… probably ok with Baltic but wouldn’t use cheap plywood for that! Also agree your face joint connecting the handlebars with screws is the most likely point of failure… probably more like several hundred pounds though. I doubt many keyboard warriors are going to break this. There ain’t of lot of 300lbs plus people who can do a pull-up… and as you’ve shown, if your fit… even with plates you’re good to go.

You've shown that a pullup with good form works. How about one with bad form? Get a buddy that doesn't work out to do some exercises without any coaching and see what kind of different forces are present. Is he pulling the cleat the wrong way, or off to one side?

@bucyrus5000

For commercial reasons I would agree 250 lbs. is a minimum test. 400 would be better imo, because, unlike office chairs, we can't expect people to be a healthy weight. I think to be idiot proof 750 lbs. (falling load) would be fall/accident resistant and not as overbuilt as one might think. To make it so strong I would double the cleat thickness and rabbet the point on the cleat to set a metal flat bar in it to strengthen the cleat (like a 1/4" x 1" flat bar cross-section). This will make it smoother to slide the items on. Further, widening the Cleat Rail plate (what gets screwed to the wall) will allow better load transfer to the studs. The wall stud can carry 3000lbs. per stud, but 20ish lbs. per screw (drywall screws). 5 screws per stud is 100 lbs. per 16". So a 16' rail could hold 1200 lbs. loaded on it (the Cleat Rail, all the hangers, and whatever else is on it). So, the things can be dialed in to meet requirements. Know your total load, the length of all (and number of studs in the wall), then you can calculate how many screws per stud will be needed (more screws means a wider Cleat Rail plate (wider Cleat Rail plate will protect the drywall too)). The Cleat will also need some consideration regarding joinery (number of screws calculated, but mitigated by glue and carpentry). Another thing that I'd love to add is a Olympic plate holder (this would be functional proof the Cleat Rail can hold massive weight). Having the hangers reach the floor is a fine idea for anything that feels bouncy, but that may require a lock-in feature on the Cleat Rail. Might be a great safety measure for everything (dip hanger, pull-up hanger, plate hanger, boxing hanger, etc.)

I'd say you have adequately tested it's use, maybe include a drop test where you take 250lbs or more and hang it and drop test it. Reality is an under-trained, overweight person (say 250lbs+ like myself) are rarely going to train pull-ups and dips unless at most they are using bands to assist and even then the much better option for strength training (5-10 reps) is pull downs and a dip assist machine. And trained heavy weight lifter is unlikely to use this design implemented with wood - a steel-reinforced design could be an interesting idea though. The other thought is to put a disclaimer saying something like "not meant as an anchor point for a pulley system."

41 myself. I was 375lbs when you posted your first video in the desert before your container build. Then I decided I wanted to build one but could never put myself on camera in that condition. Started walking and went to a 4 hour eating window. I broke into the 190s just before NYE 22 and I think im Gonna end up right around 188lbs I think and I can do pull ups and chin ups with a 45plate. Excited to see the weights! I don’t know how long ago that was now but thank you for posting content cool enough that I got inspired!

Congratulations on your channel! (Just subscribed!). I am a former surgeon and now a lifestyle medicine health coach. When it comes to low-cost, DIY weights I usually recommend to my clients to consider custom-sized sand bags.

But probably my biggest concern is in the even of dropping it on your foot or a nice wooden floors. I can't tell you how many (self-inflicted!) injuries I have seen with weights! Best of luck!

Maybe something like stall bars, to which you might be able to attach an FID bench.

The heavy bag is light enough that rope or webbing can be used to suspend the bag without drilling through plywood.

Do you always wear a hoodie while geting sunlight or only on sunny days?

When doing pull-ups or chin-ups, keep your legs straight, bending the knees only a little, so if your pull-up bar fails, you will land on your feet, not your knees. The slight knee bend will allow your legs to absorb the shock of landing, especially if you are doing weighted pull-ups.

Static weight is not different from pullup weight, theoretically. The only difference that there could be is from a quick change in momentum or if you fall down at the top of a pull-up and "catch" yourself. I may be wrong with this equation, but if you have 2.5ft long arms (an exaggeration for most people) and weigh 200 lbs, and fell to extended arms and the wood bends approximately 1 inch when you catch yourself, the equivalent static weight would be upwards of 6000lbs. Obviously this is heavily impacted by how quickly people allow themselves to lower and how stiff your bar is. If you lower yourself over the course of 1 second, the rough equivalent static weight is 470lbs. I agree with your interpretation on the failure mode of your bar. I don't think any of your equipment is likely to break without deliberate effort. I do think you could see it break at the center of the curve you have for your cut outs, just based on the geometry of the bar itself causing a pivot motion and putting that area under compression rather than tension. Probably not, though. The equations are F = ma (static) ; F = (m*a*h)/(x) (dynamic) F = Force (lbs*ft/s^2), m = mass (lbs), a = acceleration (gravity is 32.17ft/s^2), h = height of fall (ft), x = bend distance (ft)

I might be missing something and you very well could be right but let's break it down. If it failed where would it fail and what would it look like. I tend to think that the screws holding the rail to wall would fail first. That could involve them pulling out of the studs or the heads getting pulled through the plywood. Three 3-inch screws every 16 inches that go into studs is pretty significant. The wood itself could break but by my estimation based on the specs for this plywood is that the thinnest section of the pull up bar could support 800lbs static weight at the spans used. if it did fail at 13:42 what would happen? I think a twisted ankle would be the most likely outcome but certainly not the only possibility. what do you think would happen?
