Pilates Scissor You don't need any fancy equipment to work on sculpting sexy abs. Lie on your back with both legs in the air and your head and shoulders off the ground; hold your right ankle as you lower your left leg toward the floor. This completes one rep. Keep your abs pulled to your spine, and switch legs. Do 20 reps, alternating sides. Image Source: POPSUGAR Photography / Kathryna Hancock
