Lie on your stomach on the floor.
Prop yourself up on your elbows and knees, with your shoulders located directly above your elbows.
Gradually raise your knees up into the air and stiffen your body so that your entire body is straight and all of your weight is suspended between your feet and elbows. Then slowly return your body to the starting position to complete one repetition. Repeat 9 more times to complete one set of 10 repetitions.
Tip: If this exercise is too much of a challenge, you may also try plank with your weight suspended between your elbows and knees.
You’ve completed this one! Great job!
