The hips are a major part of the core and tend to be a major source of  weakness in people. When we talk about strengthening the hips, we mean the WHOLE thing. This includes your glutes, hipe flexors and extensors. The Elvis is a classic hip challenge for range of motion and abductor work, while the thread pushup forces you to activate the core and use your adductors to push the leg through. It’s all about opening and closing. In the meantime you’re working your legs and your upper body. Not bad, right? Pair this up with some jumprope and you’ll be a sweaty masterpiece.
