My strength training / prehab routine is a hybrid of that shown on the bodyweightfitness subreddit on Reddit.

I may start some participation in that, posting my progress so I’m also part of an active community with similar goals. I have three primary body weight fitness exercises on my big workout day-> L-sit, squat, and handstand. The 2nd day is auxiliary prehab exercises meant to prevent injury or reduce tension and tightness in the body that exists:

• Nordic curls: Hamstring injury prevention
• Rotator cuff strengthening including face pulls: for better upper body results and injury prevention, and aesthetics (upper back);
• Glute Medius strengthening: For reduced tightness on the outside of the leg after walking long distance.
• Other to add later: hip flexor adductor strengthening, to reduce chance of groin injury.

I read that several of the bodyweight participants also use weights and cables at times. It’s not strict no-weight policy in the forum. There are some really good concepts and I could tweak my routine eventually.
