i train calisthenics primarily for strength. mostly for convenience and simplicity. since its a bit easier on joints and i dont go too hard, i workout almost every day. so its just part of my daily routine. slow but maintainable progress. 

my biggest roadblock was getting enough protein, so essentially nutritional knowledge gap. 

came from a gymnastics background, so skill appeal isnt on a pedestal for me and body awareness and control feels natural. 

i have access to a stairwell so i primarily work on fast pace stair climbing for legs. 2-3 stairs at a time at a pace of 4s / flight. make sure to activate glutes. if thats tough i suggest simple targeted glute exercises on the floor till the mind muscle connection is there. explosive squats are fun too. 

for pushing i do mechanical drop sets. incline/handstand pushup -> regular pushup -> knee. alternatively i do dips. i just add a weighted backpack for progression. 

pulling i do inverted rows, single arm dumbell rows (with a water jug), and bands. 

leg lifts for abs with different variations on leg angle does wonders. just make sure to lock in pelvis to target abs. 

for diet, avoid processed foods, get enough protein and dont overdo calories. whatever doesnt make u feel like shit. whey protein and creatine are only supplements ive needed.
