5. HEEL TOUCHES (15 REPS ON EACH SIDE)
Lay down with your back on the ground and your knees bent and pointed towards the ceiling.
With your arms on your side raise your shoulders slightly off the ground.
Using your abs rotate your right hand down to your right foot and then back up.
Then do the same thing with your left hand.
Alternate back and forth for the desired amount of repetitions.
A flat belly workout like this not only strengthens your core, but your entire body too. It also improves your posture and performance, restores your balance and reduces lower back pain.
