2. Downward Dog
A staple in yoga, the Downward Dog position stretches out your hamstring while lightly activating your core. It can help in flexibility and mobility training. Just push your hips into a V with your palms pressed into the floor. You can alternate between this position and a plank to work the core, and you can also transition into a lunge pose or three-legged dog. There are tons of ways to work the body with this pose — get creative!
