It's hump day so obviously that means we are going to be working on growing the rump today! I want you to follow the workout as laid out. Squats should always be first! Why? If you were to swing, step up and glute bridge THEN squat, you wouldn't be able to have as big of load on your back and move with precision because you would have used most of your energy up. Doing squats first allows you to knock em out with a good and challenging weight while maintaining great form!
As always scale this workout to YOUR fitness level, adjust weights as needed.
If you've never squatted before than I advise you to only attempt them once you've learned from a fitness professional. Squats are AMAZING, not only are they working your quads, glutes and hammies but you're engaging your core like crazy--hello abs! However this is a move, that needs to be learned the right way. Jumping right in without proper knowledge and mechanics of the squat can lead to injury so train smart!
