Summary: Originally a yoga move, the side plank works your core muscles. Learn how to do side planks on stairs in this free exercise video from a personal fitness trainer.
"This exercise is called the side plank and this is a great exercise that we have adopted from yoga so we are going to incorporate the core and we are going to work on balance, stability, strength, all that great stuff to make us nice and tall in our posture and you want to come to the stairs and just place your hand on one of the steps and kind of walk your feet out and you want to lift through your torso here, extend your top arm up towards the ceiling and just hold this position and you can hold this position for about 30 seconds to a minute. You want to make sure that your hand is directly underneath your shoulder. If you have any wrist issues or shoulder issues then this may bother you so you just want to kind of release out of that. If you need to modify just lower down one knee and side plank here. You can perform this pose for about 30 seconds to a minute and then simply switch sides and that is your side plank and work that core."
