GYM: Ceiling Kick
Start in a supine position, arms by your sides and elbows bent.
Raise your legs so they are pointing toward the ceiling and above your hips.
With your feet remaining above your hips, drive your feet toward the ceiling by contracting your abdominal muscles and raising your hips off the floor. Your feet should remain above your hips as opposed to over your body.
Start with on set of 10, eventually working to three sets of 10 with a 30 second rest in between sets.
