Bring your Yoga blocks to the middle height and place them between your knees and your hips next to your thigh. Usually people tend to place them quite close to their hips, placing them closer to your knees helps to get the core squeeze that is required to lift yourself up. You can also use books or similar objects to elevate your hands. Or nothing (if you are really tough). Cross your shins. Lift yourself up and extend your legs. Now, bring one knee after another close to your chest.
