Single Leg Plank

Hold a forearm plank with one leg raised to increase demand on the midsection, primarily engaging the abdominals and obliques.

How to do the Single Leg Plank#

  1. Place your forearms on the floor with elbows under your shoulders and extend your legs so your body forms a straight line.
  2. Brace your core and squeeze your glutes to maintain a neutral spine and stable hips.
  3. Lift one leg until it is in line with your torso, keeping the knee straight and hips level.
  4. Maintain steady breathing and hold the position for the programmed time.
  5. Lower the raised leg with control and repeat on the opposite side for the next hold.

Frequently asked questions#

What muscles does the Single Leg Plank work?

The Single Leg Plank primarily works the abs, obliques. The glutes, front delts, quads, lower back assist as secondary muscles — they stabilise the movement and take over when the main target fatigues. If you feel it mostly in the glutes, front delts, quads, lower back, lighten the load and slow the lowering phase.

What equipment do I need for the Single Leg Plank?

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

Is the Single Leg Plank suitable for beginners?

Not as one of your first exercises. The Single Leg Plank is rated intermediate, so it suits lifters who already have a few months of consistent training behind them. Build the pattern on an easier variation first, then come back to it.

What are good alternatives to the Single Leg Plank?

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