Barbell Glute Bridge

Start by lying flat on your back on the ground with your knees bent and feet flat on the floor.

Place a barbell across your hips, holding it securely with both hands.

Engage your glutes and core muscles, then lift your hips off the ground until your body forms a straight line from your knees to your shoulders.

Pause for a moment at the top, squeezing your glutes.

Slowly lower your hips back down to the starting position.

Repeat for the desired number of repetitions.

Losing tension in the core or lower back partway through the movement — because Barbell Glute Bridge loads multiple joints at once, a small breakdown in bracing at the hips or spine compounds through the whole chain.

Locking out too fast or letting the elbows drift outward under load — controlling the eccentric (lowering) phase is where most of the muscle-building stimulus happens.

Using an asymmetric grip or uneven bar path, which can quietly overload one side of the body over repeated sets.

Skipping a warm-up set at lighter load/intensity — even "beginner" exercises benefit from a rehearsal set to groove the movement pattern before working sets.
