Straight Leg Hip Bridge is an intermediate bodyweight exercise for the primary: glutes secondary: hamstrings. Most lifters train it for 3 to 4 sets of 10 to 15 reps.
Lying on your back with your legs extended straight instead of bent, you drive your hips up toward the ceiling using glute and hamstring power alone. Removing the knee bend takes away the usual leg-drive assistance, making the glutes work harder to finish the lockout.
Use the straight leg hip bridge as a posterior chain accessory or warm-up activation, for 3 to 4 sets of 10 to 15 reps with a one second squeeze at the top. It belongs after your main lifts on lower body days or at the start of a session to wake up the glutes and hamstrings before deadlifts.
Set up on a mat with the heels on a firm surface; elevating the heels on a low step or bench makes it harder by increasing the range. Start with bodyweight, then progress by adding a 2 second hold at the top, elevating the heels, or moving to a single-leg version once 15 reps feel easy. The most common fault is arching the lower back to push the hips higher, so tuck the pelvis before every rep and lift only until the body is straight.
It works the glutes and hamstrings as prime movers, with the spinal erectors and core stabilising the trunk. The straight legs load the hamstrings at a longer length than a regular glute bridge.
The hamstrings are working hard in a lengthened position, which triggers cramps when they are weak or cold. Warm up with bent knee bridges, shorten the hold and build up volume over a few weeks.
It is safe when you keep the ribs down and stop at a straight line from heels to shoulders. Overextending the spine to push the hips higher is what causes lower back pinching.
The regular glute bridge isolates the glutes with the knees bent and is easier to learn, while the straight leg version adds hamstring work and a harder lever. Beginners should master the bent knee bridge first and add the straight leg version as a progression.
