Inchworm

Hinge at the hips and walk your hands forward into a high plank, then walk them back to standing; the movement emphasizes core stability throughout.

How to do the Inchworm#

  1. Stand with feet hip-width and soften your knees.
  2. Hinge from the hips and reach your hands to the floor, keeping length through the spine.
  3. Walk your hands forward until your body forms a straight high plank and brace your core.
  4. Hold a neutral plank briefly, avoiding sagging or piking of the hips.
  5. Walk your hands back toward your feet, return to a folded position, and stand up to repeat.

Frequently asked questions#

What muscles does the Inchworm work?

The Inchworm primarily works the abs. The front delts, chest, triceps, hamstrings assist as secondary muscles — they stabilise the movement and take over when the main target fatigues. If you feel it mostly in the front delts, chest, triceps, hamstrings, lighten the load and slow the lowering phase.

What equipment do I need for the Inchworm?

None. The Inchworm is a bodyweight exercise, so all you need is enough space to move through the full range of motion.

Is the Inchworm suitable for beginners?

Yes. The Inchworm is rated beginner: the technique is quick to pick up and forgiving when a rep goes slightly off. Start light and add weight once the form repeats itself without you thinking about it.

What are good alternatives to the Inchworm?

Ab Coaster, Ab Wheel, Air Bike all train the same primary muscles as the Inchworm. Pick whichever one matches the equipment in front of you.
