Front Plank With Leg Lift

Body Part: Waist

Muscle: Abs

Equipment: Body Weight

Front Plank With Leg Lift is a forearm plank variation that adds a single straight-leg lift to challenge your ability to keep the trunk steady while the hips and glutes do extra work. It trains anti-extension and anti-rotation strength, so the torso has to resist sagging, twisting, or over-arching while one leg leaves the floor. Because of that, it is more demanding than a basic plank even though the equipment requirement is only body weight.

The main emphasis is on the abs, with the obliques, hip flexors, and deep core muscles helping keep the pelvis square. The lifted leg also brings the glutes and hamstrings into the set, especially on the side doing the hold. In practical terms, Front Plank With Leg Lift is a great way to train how the trunk and hips work together during locomotion, sprinting, and any movement where one leg has to move while the body stays organized.

The setup matters more here than in many core drills. Place your forearms on the floor with the elbows under the shoulders, press through the forearms, extend both legs straight back, and tuck the toes so the body starts in a long line. A small posterior pelvic tilt and a hard glute squeeze help keep the lower back from taking over when the leg lifts. If the shoulders drift behind the elbows or the hips are already sagging, the lift usually becomes a back-extension exercise instead of a plank.

During the rep, lift one straight leg only a few inches until it is in line with the body or just above it, then pause without letting the pelvis rotate toward that side. The support leg should stay active, and the rib cage should remain down so the chest does not flare open. Lower the leg slowly, reset the plank, and switch sides if the program calls for alternating reps. The quality goal is a quiet torso, not a high kick.

Front Plank With Leg Lift is useful as an accessory core exercise, a warm-up drill before lower-body training, or a finishing movement when you want the abs and glutes to stay honest under fatigue. It is also a good option for athletes who need trunk stability without spinal movement. Keep the lift small, keep the neck relaxed, and stop the set as soon as the hips start rocking or the lower back starts arching.

Instructions

• Set your forearms on the floor with your elbows directly under your shoulders and your hands relaxed or lightly clasped.
• Extend both legs straight behind you, tuck your toes, and separate your feet just enough to keep the plank stable.
• Press your forearms down, lift your knees off the floor, and make one straight line from head to heels.
• Tighten your glutes and draw your ribs down so your lower back does not sag before the leg lift starts.
• Shift only enough weight to stay balanced, then lift one straight leg a few inches off the floor.
• Keep both hips facing the floor and avoid letting the lifted-side hip open or roll upward.
• Pause briefly at the top of the lift, then lower the leg slowly until the toes return near the floor.
• Repeat on the same side or alternate sides according to the plan, keeping each lift smooth and controlled.
• Finish by lowering both knees to the floor and resetting the plank safely.

Tips & Tricks

• Lift the leg only a few inches; a bigger kick usually comes from lumbar extension instead of glute work.
• Keep the toes of the support leg pressing into the floor so the plank does not drift forward onto the shoulders.
• Squeeze the glute of the lifted leg as if the heel is reaching straight back, not up toward the ceiling.
• If your hips rotate, widen your feet slightly and shorten the lift before the set gets sloppy.
• A hard exhale at the top of the lift helps keep the ribs down and the front of the core from flaring.
• Avoid locking the elbows or shrugging into the shoulders; press the forearms down and keep the neck long.
• Slow lowering exposes weakness faster than a fast kick, so use a deliberate return on every rep.
• If the lower back feels more active than the abs, reset the plank with a smaller leg range and a stronger pelvic tuck.
• Use this as a quality drill, not a high-rep burn set, once the trunk starts wobbling side to side.

Frequently Asked Questions

What does Front Plank With Leg Lift train most?

It primarily trains the abs and deep core to resist sagging and rotation while the glutes lift one leg off the floor.

Should my hips stay level during Front Plank With Leg Lift?

Yes. The goal is to keep both hip points facing the floor while the leg lifts, even if that means raising the leg only a little.

How high should I lift the leg in Front Plank With Leg Lift?

Only high enough to clear the floor and keep the pelvis square. If the lift turns into a back arch, it is too high.

Why do I feel Front Plank With Leg Lift in my lower back?

That usually means the ribs are flaring or the pelvis is tipping forward. Shorten the lift, squeeze the glutes harder, and keep the abdomen braced.

Can beginners do Front Plank With Leg Lift?

Yes, but many beginners should start with a standard forearm plank or a shorter hold before adding the leg lift.

Do I alternate legs or do one side at a time?

Either works. Alternating keeps the work balanced, while same-side reps can be useful if you want more control and less shifting.

What is the biggest mistake in Front Plank With Leg Lift?

Letting the hips twist or hike as the leg lifts. The movement should stay small and quiet through the torso.

How can I make Front Plank With Leg Lift easier?

Widen your feet, lift the leg lower, or hold a basic forearm plank until you can keep the pelvis steady.
