Looking to kick your plank up a notch?!
What about trying it against the wall!!! This exercise requires a lot of core strength and it is a great way to work your plank on a whole new level.
All you will need is your body and a wall!
Try for 3 sets of 60 seconds each. If you can only put one foot on the wall at a time that's a great start! Just make sure to switch feet halfway through!
