Strength / Weight Training

I’m not at gymnast or Chris Heria level at callisthenics or anything, but can give some tips.

Basic principle for progression is to do an easier form of an exercise and when you Increase the number (whether reps or time) to a satisfactory level, do a harder version and so on. I’d say 20-30 reps or 20-30 second hold is a good range to get to for most exercises before trying a harder version.

You’ll find guides on pull-up progressions, pushups, planche progressions, front lever progressions and so on. Even the basic gymnastic progressions are incredibly hard, so it’s good to get a decent amount of body weight scaled strength first.

Lower body is pretty neglected in comparison, due to them already being relatively stronger compared to arms.
For calisthenic techniques having lighter legs makes it quite a lot easier!
Gymnasts have strong legs too, but in contrast to static strength and time under tension for the upper body, lower body is very explosive and plyometric.

Key starter moves to work on:

Upper body:
Pullups / chin-ups
Dips
Push-ups

Core:
Leg raises
L sits
Ab roller

Lower body:
Body weight squats
Pistol squats
Jumps, box jumps

Equipment that’s useful to have:
Pull-up bar
Resistance bands
Push-up bars/paralettes
Gymnastic rings

Kettlebells are a whole other thing, but great for adding weight and functional muscle recruitment. I like how they train your muscles to fire contract in a coordinated way, which is great for martial arts power generation.
