Reverse Air Cycling is a dynamic core exercise that targets the lower abdominals and obliques while improving hip flexor mobility through a backward pedaling motion. It is highly effective for developing trunk stability and coordination without the need for equipment.

Setup

  1. Lie flat on your back on a mat with your arms resting at your sides, palms down.
  2. Lift both legs off the floor and bend your knees to a 90-degree angle (tabletop position).
  3. Press your lower back firmly into the floor to engage your deep core and eliminate any arch in the spine.

How to do it

  1. Begin a 'reverse' pedaling motion by extending one leg forward and down toward the floor, then pulling the heel back toward your glutes.
  2. Scoop the foot upward toward your chest to complete the circle while the opposite leg begins its extension.
  3. Inhale as the leg extends away from the body and exhale forcefully as you pull the knee back toward your torso.
  4. Maintain a slow, controlled tempo, focusing on smooth transitions between the alternating legs.

Form checklist

  • Keep your lower back in constant contact with the floor; if it arches, raise your legs higher.
  • Ensure the movement is a fluid circle rather than a simple kick-back motion.
  • Keep your neck and shoulders relaxed to avoid unnecessary tension in the upper body.
  • Maintain a 90-degree bend in the knee during the 'scoop' phase to keep the focus on the lower abs.

Pro tips

  • To maximize oblique engagement, focus on the 'scooping' phase of the circle, imagining you are pulling a heavy weight back with your heels.
  • Slow the tempo down significantly—a 3-second circle per leg—to increase time under tension and eliminate momentum.

Make it harder

  • Perform the movement with your legs closer to the floor (lower angle) to increase the lever length and core demand.
  • Lift your head and shoulder blades slightly off the mat into a 'hollow body' position to engage the upper abdominals throughout the set.
