There are loads of exercises for the backside, one of the go to exercises & quite rightly so is the squat, add in also the popular deadlift & lunges but you have to keep in mind these are knee dominant & primarily work the quads & the anterior chain (front of the leg), by doing the "glute bridge" you'll see it's a hip dominant exercise, (posterior chain) back of the leg which will target & fire much more muscle fibers hitting both glutes & hamstring...try this one after 12-15 repetitions you'll be screaming "fire in the hole"
How to do it: Sit on the floor & put your back onto the platform with as little gap as possible, be sure to use a pad or a towel for extra comfort on the bar then with your knees bent and your feet flat on the floor. Raise your hips so your body forms as straight line from your shoulders to your knees. Pause in the up position for 2-4 second, then lower your body back to the starting position.
Fit tip : I will be doing a video series on the glute & posture what effects your performance & how to active & alleviate back pain so please look out for this in the shop..😁
