Spider Lunges: Make sure to keep your shoulders over your hands and your hips as low as possible. When you place your foot down, get it as close to your hand as possible making sure to press the sole of your foot into the floor – avoid keeping the heel raised.

Oblique Planks: Keep your body in a straight line making sure your shoulder is over your elbow. Focus most on pushing the hips UP. Dropping down allows for range of motion, but that’s not where your obliques are working the most.
