Side Lying Outward Knee Kick

Body Part: Hips

Side Lying Outward Knee Kick is a bodyweight hip and glute exercise that trains the outer hip to open, lift, and control the leg without rolling the torso backward. It is a useful choice when you want to wake up the glute medius area, improve single-leg stability, or add a low-load accessory drill before heavier lower-body work. The movement looks simple, but the quality depends on keeping the pelvis stacked and letting the hip do the work.

In the starting position, you lie on your side with the lower arm under your torso for support and the top hand available for balance on the floor. The legs stay bent and slightly in front of the body so the hips do not twist open. From there, the top knee drives outward and slightly upward, then the leg extends through the hip as the outer glute stays in control. The goal is a clean arc, not a swing from the low back.

This exercise is especially useful if you feel your hips collapse in squats, lunges, step-ups, or running stride work. Side Lying Outward Knee Kick helps teach the outer hip to stabilize the pelvis while the leg moves away from the midline. Because the load is low, it works well for warmups, activation sets, and higher-rep accessory work where you want tension and precision more than brute force.

The main mistake is letting the top hip roll open and turning the movement into a torso rotation. Another common error is driving the leg with momentum instead of a deliberate lift from the outer glute. Keep the neck relaxed, the ribs down, and the motion controlled so the knee and foot travel together instead of the knee leading while the ankle collapses.

Use Side Lying Outward Knee Kick as a strict drill, not a speed exercise. When it is done well, you should feel the outer glute and side hip working more than the front of the hip or the lower back. Beginners can use this movement easily, but they still need a stable side-lying position and a small range that they can repeat without wobbling. Once that pattern is clean, the exercise becomes a reliable way to build hip control and better lower-body mechanics.

Instructions

• Lie on your side on a mat with your lower arm under your torso and your top hand lightly on the floor for balance.
• Stack your shoulders and hips, then bring the top leg slightly in front of your body so the pelvis stays square.
• Bend the top knee and keep the foot relaxed as you set the starting angle for the outward kick.
• Brace your midsection and keep your ribs down so the torso does not roll backward as the leg moves.
• Drive the top knee outward and slightly up, letting the outer hip start the motion instead of swinging the foot.
• As the leg opens, extend it smoothly so the knee and foot travel in the same controlled arc shown in the movement.
• Pause briefly at the top when the outer hip is fully engaged, without shrugging or twisting the torso.
• Lower the leg back to the start under control, keeping tension on the side hip instead of dropping it.
• Reset the pelvis before the next rep and repeat for the planned number of repetitions, then switch sides.

Tips & Tricks

• Keep the hips stacked; if the top hip rolls back, the outer glute loses tension and the front of the hip takes over.
• Use a small, clean arc if you feel the lower back helping the lift.
• Let the knee lead the outward path, but do not let the foot whip the leg open.
• Keep the top foot relaxed or lightly flexed so the ankle does not drive the motion.
• Stop the rep before the pelvis shifts; a smaller range is better than a wobbly high kick.
• Exhale as the knee opens and lift starts, then inhale on the controlled return.
• If the side of the hip cramps, shorten the range and slow the lowering phase.
• Place the top leg slightly in front of the body to keep the tension on the outer glute instead of the hip flexor.
• Use slow repetitions and a brief top pause to keep the movement honest and avoid momentum.
• If your shoulder sinks into the floor, adjust the forearm support before the set gets sloppy.

Frequently Asked Questions

What does Side Lying Outward Knee Kick work most?

It mainly trains the outer hip and glute area on the top leg, especially the muscles that help the pelvis stay level during single-leg work.

Should my top knee or my foot lead the kick?

The top knee should lead first, with the foot following in a smooth arc. If the foot snaps open ahead of the knee, the movement usually turns into a swing.

How far should I open the leg in Side Lying Outward Knee Kick?

Only as far as you can keep both hips stacked and the torso quiet. Once the pelvis starts rolling, the useful range has already ended.

Can beginners do Side Lying Outward Knee Kick?

Yes. It is a beginner-friendly drill as long as the range stays small and the side-lying support position feels stable.

Why do I feel this in the front of my hip?

Your top leg is probably drifting too far in front or the pelvis is rotating backward. Reset the hips, reduce the range, and keep the lift coming from the outer glute.

Do I need equipment for Side Lying Outward Knee Kick?

No equipment is required beyond a mat or soft surface. You can add a light ankle weight or band later, but the bodyweight version should stay strict first.

Is this the same as a side-lying leg raise?

No. This version emphasizes the outward knee drive and controlled hip opening, which keeps more tension on the outer hip than a simple straight-leg raise.

Where should I feel the working side of Side Lying Outward Knee Kick?

You should feel the side of the hip and upper glute on the top leg. If the low back or waist is taking over, the setup or range needs to be smaller.
