The hip hinge is a basic movement of life. Performing it optimally will help with low back pain and hip problems.
Set up: Think length through the back of your head, set your 3-D breathing and foot tripod.
Stand arm's length from a wall.
Lift your arms up and place your hands on the wall at shoulder height.
Exhale and bend through your hips (your pelvis will roll forward) keeping your weight over your foot tripod.
Only move as far as you can continue to move through your hips
Expert tips: as you move through your hips think of letting your SITS bones open and tailbone lifting.
