@fjdajfkldajkbfejfnsiqn And you’ve been doing that for months?
Okay. There’s a bit to unpack here.
I read in another comment that you’re quite tall, I’m assuming that means your limbs are pretty long. Understand, that puts you at a disadvantage as far as the biomechanics are concerned. More distance to travel = more work to do. Basic physics, but I’m sure you know that. I say that make the point that you shouldn’t be so hard on yourself. You’re untrained, and that’s okay. You’ve already done the hard part in committing to make a change. Everything now is trial, error, and not giving up in the meantime.
As far as the sleep goes, I’m no sleep specialist, but you need to do whatever you can to sleep as well as you can. Anyone into fitness will tell you that sleep is vital to recovery, which it sounds like is your problem. I don’t know about anyone else, but if I sleep like crap, I perform like crap. Do whatever you can do sleep as well as you can. Sleep and your diet should be your priority here.
As far as repetition volume goes: assuming you just did 30 repetitions a day, that’s 150 reps a week. That’s way too much volume for someone untrained, especially with recovery issues.
That program that I outlined in a previous comment was a bastardization of the routine that we used when I went to the US Army airborne school. When I started, I struggled to do 4 chin ups, and when I left, I was doing sets of 10 comfortably. The first week, we did a set of 4 before and after chow, breakfast/lunch/dinner. The second week, we did 6. The third week, we did 8.
Admittedly, I’m also 5’7” with my T-Rex reach, so it bears repeating: don’t be so hard on yourself.
If I were you, I would take a week off. Sleep as best you can and get your protein in. Then, see where you’re at. Reevaluate from there.
Also, if a psychologist is on the table for you, might not be a bad idea to talk to one, though I suspect at least part of the stress is because you’re being too hard on yourself.
