Exercise Week: Check out this elbow-leg workout

As you can see, all you need to do to get started is to be on all fours. Then have one leg down with your elbow and the opposite leg that’s working, out behind butt cheek. Be sure the knee is not turned down.

Drive that knee until it touches the side of your elbow. Make sure you extend your leg back up above your glutes. For it to be effective, repeat up to 30 times on both sides.
