A standard glute bridge works the hips, core and glutes, but this variation adds a walkout, which places an emphasis on your hamstrings. It will strengthen and lengthen the hamstring muscles whilst activating your core, hips and glutes.
To perform a glute bridge, lie flat on your back with your arms by your sides, feet shoulder width apart and your knees bent at 90 degrees. Drive your hips powerfully off the floor by squeezing your glute muscles and pressing your heels into the ground. Your head should stay in line with your spine throughout. This is where the exercise differs from a standard glute bridge! In the bridge position, slowly walk your feet forwards whilst keeping your hips as high as possible. Once you are at full extension (this is the point just before your hips start to drop) start to walk your feet back to the starting glute bridge position. The further you walk your feet out the harder this exercise will be!
Perform this movement slowly and with control so you can focus on keeping your glutes and core engaged.
