This is a classic movement used in many exercise disciplines and it is specifically designed to work the glutes, or in layman’s terms, your bum muscles. And who doesn’t want to tone those? But because the “glute bridge” is so often taught and performed poorly, many people feel strain in their hamstrings and lower back, rather than their posteriors. If you want to perfect your own, then you have to learn how to do the perfect bridge. So... are you ready for a booty that will rival Beyoncé’s?
