How to do it

Lie flat on your back with your hands behind your head and your legs lifted with knees bent. Pedal your legs in a cycling motion, extending one leg out while drawing the other knee in toward your chest, and continue alternating in a smooth rhythm. Keep your lower back pressed into the floor and your core braced throughout.

  1. 1Feel your lower abs and hip flexors working as you pedal your legs
  2. 2through the air
  3. 3Keep the small of your back pressed flat into the floor
  4. 4Feel a steady, controlled rhythm rather than fast flailing

Common mistakes

  • Don't let your lower back arch as you extend each leg
  • Avoid yanking on your neck with your hands
  • Don't rush the pace and lose control of the motion
