This challenging exercise harnesses all your core strength to retain stability throughout the movement. "Don't let your inability to do too many reps prevent you from including this move in your workout," Kendall said. "Keep doing the v-sit and build up your strength and tone your stomach while you build your ability to do more over time."
- Lie flat on the floor with your legs together and your arms at your sides.
- Raise your shoulders a few inches off the ground, and lift your legs so they're at roughly a 45-degree angle with the floor. Bring your arms upward as though you're reaching for your legs. Do not lean your neck forward or bend your knees.
- Using the power of your abs, bend your knees and pull them toward your torso. Use your arms to guide your torso forward. Your body should make a V at the top of the rep with your weight balanced on your glutes.
- Slowly return to the starting position.
