The glute bridge is a simple, floor-based exercise that strengthens your buttock muscles and the muscles that support your lower back and hips.
The short version
- Studies using muscle sensors show it activates the main buttock muscle at a solid, moderate level, which is why it's one of the most commonly used early exercises for hip, knee, and lower back problems.
- It needs no equipment and is easy to adjust to almost any fitness level.
Why it helps
Your buttock muscles do more than shape how you look — they help control your hip and knee alignment when you walk, run, climb stairs, or stand up from a chair. When these muscles are weak, other joints, like the knee or lower back, often end up compensating and taking on extra strain.
The glute bridge is popular in rehab because it activates the buttock muscles strongly without needing any equipment or much joint movement, which makes it a good starting point for people easing back into exercise after pain or a period of inactivity. Studies measuring muscle activity during the exercise have found it produces moderate activation of the main buttock muscle — enough to make it a useful starting exercise — and adding a resistance band or lifting one leg at a time increases that activation further once the basic version feels easy.
It also asks your core to work quietly in the background to keep your pelvis level and your lower back supported through the movement, which is part of why it's often used alongside back-pain rehab as well as hip and knee programmes.
⚠️ When to skip this exercise and see someone in person
Hold off if you've had recent hip, pelvis, or back surgery and haven't been cleared to load it, or if you have sudden, severe back or hip pain with no clear cause.
- Stop and get checked if the movement causes sharp pain, or you notice numbness, tingling, or weakness spreading down your leg.
A glute bridge should feel like your muscles working, not your joints hurting.
How to do it
- Lie on your back, knees bent, feet flat on the floor about hip-width apart.
- Squeeze your buttock muscles and lift your hips up until your body forms a straight line from your knees to your shoulders.
- Hold for a second at the top, then lower back down slowly under control.
- Keep your lower back relaxed rather than arching it hard at the top — the lift should come from your hips, not from pushing your back into an extreme arch.
Start with: 3 sets of 10, most days of the week.
Progression note
Once 3 sets of 10 feels easy with good control, progress by holding the top position for a few seconds, then by lifting one leg at a time, then by adding a resistance band above your knees. Change one thing at a time so you know what's working.
Bottom line
The glute bridge is a well-studied, low-impact way to build buttock and hip strength, and it's a common starting exercise across knee, hip, and back rehab programmes. Keep the movement controlled and pain-free, and progress gradually from the basic version to more challenging variations as it gets easy.
