Alternating V-Up

1. 1 - Lie flat on your back on an exercise mat with your legs straight and arms extended overhead, keeping your body in a straight line.
2. 2 - Engage your core and simultaneously lift your right leg and your left arm off the ground, reaching your left hand toward your right foot at the top of the movement.
3. 3 - Lower your right leg and left arm back to the starting position in a controlled manner.
4. 4 - Immediately repeat the movement on the opposite side, lifting your left leg and right arm and reaching your right hand toward your left foot.
5. 5 - Continue alternating sides in a rhythmic, controlled fashion for the desired number of repetitions.
6. 6 - Keep your lower back as close to the mat as possible throughout the movement and avoid using momentum.
