Superset 1, Exercise 2: Dumbbell Skull Crusher to Bent-Leg Sit-Up
Lie flat on your back on a yoga mat, holding a dumbbell with both hands at your chest. Bend your knees and position your feet firmly on the mat. Engage your abdominal muscles by drawing your belly button in toward your spine and extend both arms to hold the dumbbell directly above your chest. This is your starting position.
Inhale and brace your core. While keeping your shoulders as still as possible, bend your elbows to lower the dumbbell just above your forehead. Exhale and extend your elbows to return the dumbbell directly overhead, ensuring that your shoulders, elbows, and wrists remain aligned.
On an exhale, keeping your heels firmly planted on the floor, slowly lift your head, shoulder blades, and torso off the floor. Lengthen your spine to sit up tall, pressing the dumbbell up toward the ceiling.
Inhale and slowly lower your torso, shoulder blades, and head to the mat, returning to the starting position.
This counts as one rep.
Complete 10 reps, then take one minute of rest. Repeat this circuit for a total of three rounds.
