15 Simple Yet Effective Ab Exercises You Can Do at Home

This classic Pilates move creates an intense burn in your lower abs.

• Lay face-up on the floor with your legs extended straight up toward the ceiling. Place your hands underneath the back of your head, or extend your arms out to the side and grip the floor for more stability.
• Pressing your lower back into the ground, slowly lower both legs down toward the floor, going as far down as you can before your lower back starts to lift.
• Slowly lift your legs back up. That's one rep. If this is too difficult, lower one leg at a time.
