FYI: These exercises are perfect for beginners.
This classic but hardcore move is what Don-A-Matrix sprinkles into every celebrity ab workout routine.
How to: Lie on your back with your legs extended out in front of you. Place your arms by your sides, palms down. You can also alternatively bend your elbows so your upper body is resting off the ground. Engage your core by pressing your lower back into the mat. Lift both legs off the ground about 6 to 12 inches from the the floor or about a 45-degree angle. With your core tight and neck relaxed, lower one leg toward the floor as you lift the other leg up. This is the start of the “scissoring” motion.
