starting to invent a new body resistance routine for the summer, so i began by doing very slow pullups with an assortment of grips using a weighted vest and ankle weights. pushups, flutter kicks, crunches, stances/holding positions, air squats, stuff like that with weighted vest, ankle, and wrist weights. then did some misc routine of punching and kicking techniques to various styles of targets. last i did a bone conditioning routine ive been inventing-as-i-go over the years. i do upper body one day a week and lower a different day of the week, and today was lower. at this point it goes something to the effect of 30 strikes each individual part im conditioning (from knees, down shins, to ankles, to all weaponized surfaces of the foot), using a hollow steel pipe, with a first few opening strikes at realistic striking force, and subsequent lowering to a forceful and well controlled tap. i started this years ago on much softer surfaces, and upgraded to wood, and finally metal and concrete. it actually starts to feel kind of good after a year of doing it.
