How to Perform 45 Degree Hip Extension:
Shoulder blades pinned back
Slight bend in the knees
Push your hips back/to the sky (drive your bum back) whilst maintaining a neutral spine (hinge at the hips)
Chase the stretch in the back of the legs (hamstrings)
Drive up by squeezing your glutes into the pad (don't hyperextend the lower back at the top)
