Lying Bent Knee Figure 8

Body Part: Hips

Muscle: Other

Equipment: Body Weight

Lying Bent Knee Figure 8 is a floor-based hip control drill that asks you to trace a smooth figure-eight path with one bent leg while the rest of the body stays quiet. It is useful when you want to wake up the hips, challenge pelvic control, and connect the glutes and deep core without adding much joint load. The movement looks simple, but the benefit comes from keeping the path clean and resisting the urge to swing the leg around.

Because the exercise is performed on the floor, the setup does most of the coaching for you. Lie back with your shoulders relaxed, your rib cage settled, and one knee bent so the hip can rotate without the low back taking over. The opposite leg should stay quiet, which helps you notice whether the pelvis is rocking or whether the motion is staying inside the working hip socket.

Lying Bent Knee Figure 8 works best when the circles are small at first. Draw the knee across the body, around, and back through center in one smooth loop, then reverse the path to complete the figure eight. The movement should feel smooth and deliberate rather than forced, with the pelvis staying heavy on the mat and the neck staying relaxed.

This drill fits well in a warm-up, a mobility block, or an accessory session before squats, lunges, running, or any workout where the hips need to move cleanly. It can also be useful on recovery days when you want low-intensity movement that still demands control. If you feel pinching in the front of the hip or your low back starts to arch, shorten the path and slow the tempo before you try to make the motion bigger.

The best repetitions look almost calm from the outside. You should be able to breathe steadily, keep your torso mostly still, and finish each rep without losing the line of the movement. Over time, progress by making the figure eight smoother, slower, and more symmetrical rather than by forcing a larger range that your hips cannot control yet.

Instructions

• Lie on a mat on your back with your shoulders relaxed, one knee bent, and the other leg extended long and quiet.
• Keep the bent thigh set over the hip and square your pelvis before you start the first rep.
• Lightly brace your midsection so your low back stays settled against the floor.
• Move the bent knee across your body in a controlled arc, letting the motion come from the hip socket.
• Sweep the knee forward and around to create the first loop of the figure eight.
• Pass back through center and trace the opposite loop with the same smooth tempo.
• Keep the nonworking leg, rib cage, and shoulders still while you breathe evenly.
• Finish the rep by bringing the knee back to the start position under control, then reset before the next rep or switch sides.

Tips & Tricks

• Make the first few figure eights small enough that your low back stays heavy on the mat.
• If your pelvis rolls side to side, shorten the loop and slow the knee as it crosses center.
• Keep the nonworking leg quiet instead of letting it help steer the movement.
• Exhale as the knee travels across the body to help keep the ribs from flaring.
• Let the hip rotate instead of forcing the knee with your foot or ankle.
• A smooth rep is better than a bigger rep if the front of the hip feels pinched.
• Use the same tempo in both directions so one side does not dominate the pattern.
• Stop the set when you start lifting your shoulders or chasing momentum with the leg.

Frequently Asked Questions

What does Lying Bent Knee Figure 8 work?

It mainly trains hip control, with the glutes and deep core helping keep the pelvis steady while the bent leg traces the pattern.

Is Lying Bent Knee Figure 8 a stretch or an exercise?

It sits between the two: you get a gentle hip mobility effect, but the real challenge is controlling the movement instead of just relaxing into the position.

Should My Knee Stay Bent The Whole Time?

Yes. Keep the knee bent so the hip can rotate through a cleaner path and the motion stays focused on the working side.

Why Does My Low Back Arch During Lying Bent Knee Figure 8?

That usually means the circle is too big or the hip has run out of control. Make the loop smaller and keep your ribs and pelvis quieter.

How Big Should The Figure Eight Be?

Start with a small, smooth loop that you can repeat without shifting your torso. Bigger is not better if the pelvis starts rocking.

Can Beginners Do Lying Bent Knee Figure 8?

Yes. Beginners should keep the motion slow, use a short range, and stop before the hip or low back feels strained.

When Should I Use Lying Bent Knee Figure 8 In A Workout?

It works well in a warm-up or mobility block before lower-body training, or as a low-intensity drill on recovery days.

What Should I Feel If I Am Doing It Right?

You should feel the hip and glute working to guide the path, with the core helping keep your torso from twisting.
