any tips? mainly for exercise and for shoulder exercise just dont want to hyperextend my elbow or dislocate my fingers,etc. I just mainly just do 2 punch jab combos as hard as i can over and over Im not that fit so it gets the heart rate up and body punches. I dont do too many hooks because i sometimes graze it and hurt the little knuckles. I do a few roundhouse to the hips but have to watch out I dont kick my toe on the boxing stand. i get tension headaches as well afterwards.
