I'm a 5'11 18yo 79kg male, waist 32 inches (in the morning). I struggle with pull-ups, I think this is due to:
- excess body fat
- lack of muscle
- my disproportionately long arms (I don't have specific measurements but I know they're longer than my height).
I am a beginner in fitness. I've been going to the gym for a month, but I ran long distances before that. On the Smith Bench Press, I can do 70kg for 5-8 reps, 3 sets (incl. bar weight), and Smith Squat 90kg for 10 reps, 3 sets (incl. bar weight). In terms of bodyweight exercises, I can do ~30 wide grip pushups, and ~12 narrow grip close-to-the-chest pushups (ie. to work my triceps more). I can do assisted pullups with ~30kg support, 10-12 reps, and 3 sets. All of these are, to the best of my knowledge, good form. However, I struggle to do even a single pull-up. I've noted that my arms seem to be my weakest point, even in bench/lat pulldown/etc, my arms fatigue far more quickly than my chest/back/anything else. I would like to do pullups so that I can do a full-body workout even when I don't have access to a gym (variations of bodyweight pushups, pullups, and squats). I see a few options to achieve this: lose body fat, and gain muscle. Which of these would be best in my position?
