Nice job man so train like this: 3-5 sets 2 min rest of push-ups leaving 1-2 reps in the tank so if your max is 6-7 substract 1-2 and do that for sets and on last set you go to max reps. Then do 3 sets of easier variation same protocol so it would be knee push-ups and that’s it ;-)

Almost man just straighten your knees completely and tense your legs besides that yeah keep going;)

Get out of here if you’re not into calisthenics

Keep going man and you’ll get far don’t stop

So start like this do negatives and rows rows can be done either rings or with a table or a broom between two chairs or simply two chairs. Do 3-5 sets of 5-8 negative pull-ups so you jump up and hold at the upper position and come down slowly in 3-5 seconds down controlled as much as possible then do 3-5 sets of 8-12 reps of rows leaving 1-2 reps in reserve and last set going to failure. And that’s it and finish with dead hang just hanging on bar as long as you can 2-3 max sets
