James Shapiro, NASM-certified personal trainer in NYC and owner of Primal Power Fitness, told us that V-ups "require a lot of muscle activation and coordination for both the up and downward motion."
- Lie on your back, and lift your legs and arms up so they are extended toward the ceiling. Lift your upper back off the floor, reaching your hands toward your feet.
- Lower your arms and legs toward the floor while keep your arms overhead, keeping your shoulders off the mat and lower back pressed into the mat. This is one rep.
- James suggests completing anywhere from 14 to 20 reps.
- For more variation, James says to alternate with opposing limbs or add light dumbbells.
