Best Bodyweight exercises to train core (Part 2)

9. Reverse Crunch

Starting by lying down on your back pressed against the floor with your legs fully extended, your arms rest along your sides, and your palms placed on the floor. Slowly move your legs up until your thighs are perpendicular to the floor and your feet are together while breathing in. Then, move your knees toward your chest as you roll your pelvis backward and pull your hips and upper back off the floor. Hold this position for 10 seconds, then exhale as you roll your legs back to the starting position.

Trainer Tip: Keep your arms resting straight along your sides throughout this movement.

10. Seated Scissor Kick

Starting by lying down with your back pressed against the floor, your legs and arms fully extended to each side with your palms facing down the floor. From a slight bend in your knees, pull your legs up so that your heels are about 5- 6 inches off the ground. Engage your abs and roll your back slightly off the floor. As if your legs were a pair of scissors, move them by alternating crossing one extended leg over the other, while keeping your abs flexed at all times.

Trainer Tip: Don’t let your back round up. Engage your abs tight to maintain a strong, straight spine. For increasing intensity, raise your arms up and roll small, slow clockwise circles with your shoulders while you kick your legs in scissor movement.

11. Superset With An Aerobic Exercise
Even with extra exercises and more challenging movements, it can still be hard to train your abs enough to make them pop. Try supersets by adding an aerobic core movement to each exercise to train your core in a different way,and burn extra body fat that normally hides that six-pack.
To add aerobic supersets to your ab routine, try combining hanging leg raises with mountain climbers or combine burpees with an wheel. Rest as little as possible between reps. Adding these extra aerobic core-oriented exercises doesn’t seem like much, but after 8-10 of these supersets, you’ll know the difference!
