Primary Muscle Group: Core Muscles
Muscle groups worked in this exercise: Rectus Abdominus, Internal and External Obliques
Preparation: Lie on your back and bend your knees and place your feet on the floor about hip-width apart. Place the resistance band across both arches and lift your feet towards the ceiling. Hold onto the ends of the band with your hands.
Execution: Lift your upper body up so that your shoulder blades are just above the floor; inhale. Now, slowly lower your legs, exhaling and keeping your hands stationary stretching the band. Stop at the point that your lower back comes off the floor. Inhale as you rise to the starting position.
Comments: You'll really work your torso harder trying to remain stable with the use of the resistance band.
