Planks are one of those exercises that never seem to get easier no matter how often I do them, and I'm OK with that — I like a challenge! One of my favourite dynamic plank variations is the plank to pike because it simultaneously challenges core stability and strength, and I always feel it working after a few reps.
Jada Pinkett Smith likes this move, too, and showed us how to perfectly execute it in a recent video she posted on her Instagram. If you're looking for new ab exercises that require absolutely no equipment, this one should definitely be on your list. Grab a pair of socks and get ready to work! Smith makes it look easy, but trust me when I say that you're going to be shaking by the fifth rep.
Check out Smith's form in the video above, and if you're up for a challenge, try the plank to pike out for yourself.
