The air bike (version 2) is a body-weight core exercise that primarily targets the obliques, with the rectus abdominis, gluteus maximus, and quadriceps assisting through the pedaling motion. Performed lying on your back while cycling your legs and rotating your torso, it trains rotational core strength and works the full midsection with no equipment needed.

How to do the Air Bike (VERSION 2)

  1. 1Lie flat on your back on a mat with your lower back pressed gently into the floor.
  2. 2Place your hands lightly behind your head, fingers supporting but not pulling on your neck.
  3. 3Lift both feet off the floor and bring your knees up so your thighs are roughly vertical.
  4. 4Curl your shoulders up off the mat to engage your abdominals and begin the movement.
  5. 5Rotate your torso to bring one elbow toward the opposite knee while extending the other leg out straight.
  6. 6Switch sides in a smooth pedaling motion, drawing the opposite elbow to the now-bent knee as the other leg extends.
  7. 7Keep alternating sides under control, breathing steadily, until you complete your reps.
  8. 8Lower your feet and shoulders back to the mat to finish the set.

Form tips

  • Rotate from your torso, turning your shoulder toward the knee rather than just swinging your elbow across.
  • Keep your lower back in light contact with the mat to protect your spine and keep tension on the abs.
  • Move slowly and deliberately — controlled reps build more core strength than fast, sloppy pedaling.
  • Extend the straight leg as low as you can while keeping your back flat; raise it higher if your back starts to lift.

Common mistakes

  • Pulling on your neck with your hands, which strains the cervical spine instead of working the abs.
  • Letting the lower back arch up off the mat as the leg extends, which removes tension and risks the spine.
  • Rushing the pedaling motion so momentum does the work instead of the obliques.
  • Only moving the elbows side to side without rotating the torso, which barely engages the obliques.

Frequently asked questions

What muscles does the air bike work?

It primarily works the obliques, with the rectus abdominis, gluteus maximus, and quadriceps acting as synergists during the rotation and pedaling motion.

Is the air bike good for beginners?

Yes. It uses only body weight and can be scaled by slowing the tempo or keeping the extended leg higher, making it accessible while still challenging the core.

How many reps should I do?

A common range is 2–3 sets of 15–20 reps per side. Focus on controlled rotation rather than speed, and stop when your form starts to break down.

Where should I feel the air bike?

You should feel it mainly along the sides of your waist (the obliques) and across the front of your abs. Sharp neck or lower-back strain means your form needs adjusting.
