When we say hinge, we mean the movement that occurs at your hips with bending and straightening.  

It’s hard to appreciate the importance of this movement to your strength, stability, and function. As you get older, it becomes more challenging to hinge—to touch your toes and to stand back up.

The muscles you use in a hip hinge are the same ones that let you walk and run, as well as jump and climb stairs.  

A proper hip hinge is surprisingly difficult to do. Kids do it no problem. However, with years of sitting you lose the flexibility and strength in your posterior chain—glutes, hamstrings, and low back, as well as core stabilizing muscles.
