Forearm Plank
With toes tucked, lower down onto your elbows and forearms. Keeping the hips in line with the shoulders and your knees off of the ground, stack your shoulders over your elbows, which should be no wider than shoulders distance apart. Keep the back of the thighs pressing up towards the sky, while guiding the heels back and the heart forward. Maintain a strong core and hold here for 30 seconds.
