Single Leg Bridge With Hip Flexion

Body Part: Hips

Muscle: Glutes

Equipment: Body Weight

Single Leg Bridge With Hip Flexion is a floor-based glute exercise that asks one side to hold a bridge while the other leg stays lifted in a hip-flexed position. The setup looks simple, but the raised leg changes the balance demands and makes the working side do more of the stabilizing work through the pelvis, trunk, and hip.

The main training effect comes from the glute on the planted side, with the hamstrings helping at the bottom and the core working to keep the ribs and pelvis stacked. That combination makes the exercise useful when you want unilateral glute work without needing external load. It is especially helpful for building control in a bridge position, cleaning up side-to-side differences, or preparing for harder single-leg lower-body work.

The position of the free leg matters. Keeping that knee and hip flexed reduces swinging and helps you avoid twisting through the low back. If the lifted leg drifts, straightens, or drops while you bridge, the set usually turns into a compensation pattern instead of a clean hip extension drill.

Good reps should feel like the pelvis rises as one unit. Drive through the planted heel, lift the hips until the body forms a straight line from shoulder to knee, then lower with control before the low back takes over. The goal is not to throw the hips high; it is to keep the working glute active while the ribs stay down and the trunk stays steady.

This movement fits well in warm-ups, accessory work, glute-focused sessions, and rehab-style training where you want bodyweight control more than maximal load. Beginners can usually learn it quickly, but they still need a stable floor setup and a manageable range of motion. If the hamstring cramps or the low back arches, shorten the bridge and reset the pelvic position before continuing.

Instructions

• Lie on your back with one foot flat on the floor and the other leg lifted so the hip and knee stay bent above your torso.
• Place the planted foot close enough that your shin is near vertical and your heel can drive into the floor without your hips twisting.
• Keep both arms relaxed on the floor for balance and set your shoulders flat before you start the rep.
• Brace your ribs down and lightly tuck your pelvis so your low back stays neutral before lifting.
• Press through the planted heel and squeeze the glute to raise your hips until your body makes a straight line from shoulder to knee.
• Hold the lifted knee in hip flexion instead of letting it drift outward, drop, or straighten as you bridge up.
• Pause briefly at the top, then lower your hips slowly until the glute is just above the floor.
• Reset your pelvis and breathing at the bottom, then repeat for the planned reps before switching sides.

Tips & Tricks

• Put the planted foot close enough that your knee stays roughly over your ankle at the top; if the foot is too far away, the hamstring usually takes over.
• Keep the lifted thigh quiet and the knee shape fixed. If the free leg swings, the pelvis usually starts rotating with it.
• Think about lifting the hips by squeezing the working glute, not by arching the lower back higher.
• A small pause at the top makes the bridge cleaner than trying to chase maximum height.
• If the hamstring on the planted side cramps, lower the foot slightly farther away and reduce the top range for a few reps.
• Keep the ribs stacked over the pelvis; flaring the ribcage is a common way to turn this into a low-back extension exercise.
• Move slowly enough that you can keep the lifted leg in the same hip-flexed position from start to finish.
• Use a mat or soft floor surface so the shoulder blades and sacrum can stay comfortable during repeated reps.

Frequently Asked Questions

What does Single Leg Bridge With Hip Flexion work most?

The planted-side glute does most of the work, with the hamstring and core helping keep the pelvis level during the bridge.

Can beginners perform this exercise?

Yes. Start on the floor with body weight only and keep the bridge small until you can hold the lifted leg steady without twisting.

Why is the free leg kept in hip flexion?

Holding the free leg bent and lifted makes the exercise more stable and keeps the pelvis from rotating as you bridge.

Why do my hamstrings cramp during the bridge?

The planted foot is probably too far from your hips or you are lifting with the back instead of the glute. Bring the heel a little closer and shorten the range.

Should I feel my lower back working in Single Leg Bridge With Hip Flexion?

No, the lower back should stay stable. If you feel it taking over, keep the ribs down and stop lifting when the hips are in line with the knee and shoulder.

How high should my hips go?

Only high enough to make a straight line from shoulder to knee on the working side. Going higher usually means the low back is extending instead of the glute finishing the rep.

What can I use instead of Single Leg Bridge With Hip Flexion?

A regular single-leg glute bridge is the closest swap. If you need less balance demand, keep both feet on the floor and do a standard glute bridge.

Where should my shoulders and arms be during the set?

Keep your shoulders flat on the floor and let your arms rest out to the sides for balance. They should help you stay steady, not push the rep up.
