i do 15kg x 20 rep on both 5 sets folowed by 3 x 3 min rounds in the plank which is a killer do that 4 days n he ova 3 i do a different ab workout wer: - i raise my legs 6 inch off ground and hold - then i raise my shoulders keeping my lower back on the floor with my legs 6 inch off ground x 25 reps - then without letting either foot hit the ground i bring my foot over onto my opposite knee n keepin my feet 6 inch off ground do 25 reps on each side - then il do leg raises up 6 inch down 6 inch x 25 reps during the workout dont let ur feet hit the ground
i dont think all the muscle in the world is really going to help take a punch... get you a sparring partner to hit you everyday in the body part that you like?
i use the small handheld medicine ball 4lb i beat my ribs and all with it ,it works well. moving to a heaver one soon.
