I mostly do shadow boxing and hard surface kicking (old boat) with construction shoes (front/straight kicks mostly, circular can turn dangerous with those shoes). I don't have equipment except a pull up bar, a jump rope, and a barbell I use like a bo staff (basic left/right/left/right crosses like strikes at torso level like a madman, for both power and stamina, some basic spins, old and spin at arms length). I don't go to the gym, too much NPCs on spinning wheels. The rest is classic, pushups, series of jumps, nothing fancy just moving stuffs/dynamic stuffs. Because the main problem of body building is "staticity", like you train your body to remain camped during effort, that's not a good habit and that's what the body will reproduce during stressful situation, like combat. But I have nothing against power training, to be clear
