7. Medicine ball push-ups

Start in a push-up position, instead this time place both hands on top of a medicine ball. Slowly lower into push-up in four counts, keep abs braced, and push back into starting position. Now remove your right hand and place it on the floor in line with the ball so hands are about half a metre apart. Do another push-up. Return your hand to the ball. Do another push up. Move left hand out to the side and do another push up. Continue this 10 to 20 times and do three to four sets.

Why it works

Incorporating an uneven surface like the medicine ball helps increase your balance and core stability.
