High Plank Leg Raise

Holding a high plank, you lift one straight leg a few centimetres and hold before switching, cutting the base from four points to three. The instant the foot floats, the abs and glutes must stop the hips from twisting — and that fight is the exercise. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Level — Beginner

Intermediate — a stillness test; the waistband, not the leg, is what observers should watch.

Proper form — 5 cues

  1. Squeeze the glute of the working leg before the foot leaves the floor.
  2. Raise the heel no higher than hip height — higher only tips the pelvis.
  3. Keep the pelvis flat as a tabletop while the leg floats.
  4. Press evenly through both palms without leaning away from the lifted side.
  5. Lower the toes silently and switch legs with zero hip sway.

Breathing: Exhale during each lift and hold, inhale as the foot returns.

The 3 mistakes Maddy corrects most

Swinging the leg up with momentum. The kick launches the pelvis into rotation, replacing the slow stabilising work with a wobble to recover from. Fix: Lift on a two-count as if the heel were pushing through honey.
Bending the knee of the lifted leg. A bent knee shortens the lever and hides the glute's job of holding a long straight line. Fix: Reach the heel away from the crown of the head throughout the lift.
Shoulders creeping toward the ears through the set. Rising tension in the neck signals the upper traps are compensating for a fading plank. Fix: Re-press the floor and lengthen the neck between reps, or end the set.

Common questions

What does lifting the leg add to a normal plank?

Two demands the static hold never makes: the glutes must extend the hip against gravity while the trunk holds its line, and the abs must resist the twisting pull created by losing one anchor. It converts a passive endurance hold into an active stability drill without any equipment or extra space.

How high should the leg go?

Barely — somewhere between ankle height and hip height is the honest window. Past hip height the movement stops coming from the hip and starts coming from lumbar arch and pelvic tilt, which is fake range. Judge each rep by the stillness of the waistband, not the altitude of the foot.

Can beginners use this before mastering the full plank?

Better to bank the prerequisite first: hold a clean thirty-to-forty-five-second high plank, then add the leg lifts. Attempting the raise on an unstable base rehearses hip sway rather than preventing it. The kneeling plank followed by the standard hold is the fastest honest route to this drill.
