Lie down on your back. Place your hands lightly behind your head, elbows out to the sides. Lift both legs off the ground and bend your knees at a 90-degree angle. Drive your right knee towards your chest while simultaneously twisting your left elbow to meet it. Return to the starting position and repeat with the opposite side, driving your left knee towards your chest and twisting your right elbow to meet it. Continue alternating sides, as if pedaling a bike, in a smooth and controlled motion.

How to perform the Air Bike

  1. Set up. Set up in a stable, balanced starting position appropriate for the Air Bike using your body weight.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
