To build a rock hard body, you need to exercise regularly. Ab and boxing workouts can help you burn a ton of calories and strengthen your body. These two boxing ab workout systems allow you to do both and push your body harder:
TITLE Precision Punch Incline Ab Board: this bench offers adjustable height inclines to allow you to push yourself harder. It also features a punching ball with rapid-recoil spring for intense fat burning exercises.
AbJab XT: it combines punching with ab training to push your body harder. The harder and longer you punch, the better.
