This week our challenge is Planks! Planks are a great core workout without having to do endless sit ups .
Start on elbows and knees, locking hands together. Straighten legs and raise your body so that you’re supported by the balls of your feet, with feet hip-distance apart. Face the floor, being careful not to arch your back or stick your bottom in the air. If your stomach is shaking then you’re in the right place :). Hold this position for 30 seconds to begin with, extending the time as you get stronger. Try is 3 days a week 3 sets of 30 second holds.
*To modify this, you can put your knees on the ground.
