  • Timed hold
  • Hips
  • Lower legs

The Standing Air Bike is a functional core exercise that targets the rectus abdominis and obliques while improving balance and hip flexor strength. It serves as an effective low-impact alternative to floor-based bicycle crunches, engaging the quadriceps for stability.

Setup

  1. Stand with your feet hip-width apart and your spine in a neutral, upright position.
  2. Place your fingertips lightly behind your ears with your elbows flared out wide to the sides.
  3. Engage your core and maintain a slight bend in your knees to stabilize your base.

How to do it

  1. Lift your right knee toward your chest while simultaneously rotating your torso to bring your left elbow toward the rising knee.
  2. Exhale sharply during the rotation, focusing on the contraction of the obliques and abdominals.
  3. Inhale as you return to the starting position with control, ensuring your foot lands softly.
  4. Immediately repeat the movement on the opposite side, alternating in a fluid, rhythmic tempo.

Form checklist

  • Rotate from the mid-back (thoracic spine) rather than just pulling your elbows forward.
  • Keep your chest open and avoid pulling on the back of your head or neck.
  • Drive the knee up toward the midline of the body to maximize lower abdominal engagement.
  • Maintain a strong, stable standing leg without locking the knee out completely.

Pro tips

  • Focus on bringing the shoulder toward the opposite hip, rather than just the elbow, to ensure full oblique recruitment.
  • Pause for a split second at the peak of the contraction to emphasize the mind-muscle connection with your core.

Make it harder

  • Slow the tempo down significantly, taking 3 seconds to lower the leg to increase the balance and stability demand.
  • Add a small explosive hop as you switch sides to increase the heart rate and turn the movement into a plyometric core exercise.
