So, the basic hip hinge in functional training IS a straight leg, soft knee, movement. In skiing the knees and ankles bend or flex also which is more of a bend and lift movement pattern in functional terms. I think it's still applicable across the board for practical purposes when trying to explain the diffference between spinal and hip flexion though. A great way to learn both the hip hinge for skiing and work on matching angles is to take a broomstick or similar and hold one end against one shoulder and the other end against the opposite buttock or hip and then do squats in front of the mirror so you can see your angles. The trick is to keep constant contact at both ends of the stick throughout the movement. So the reason Gray Cook says not to hip hinge ( straight leg ) is virtually the same reason we are saying not to tuck the pelvis while skiing. In a straight leg hip hinge the imbalance that is not allowing you to touch your toes, be it tight hamstrings or what not is going to cause counternutation to the pelvis ie: the same as tucking the pelvis during the hinge thereby reducing your natural curvature or flattening the lower back out of neutral postition and putting it in a compromised position. That being said, when you add ankle and knee flexion to the hinge, these imbalances are shortened as opposed to lengthened so the pelvis should be able to function normally whether or not you can touch your toes, so perfectly safe.Thank you, this is exactly what I was looking for yesterday but couldn't find it. I'm the skier that's "flexed though the spine" in the 1st picture. However, when I tried to teach myself the hip hinge I hyperextended the lower spine. One point that is missing is Gray Cook says don't hip hinge if you can't toe touch. The 1st thing my trainer taught me was toe touching. When I figured that out he taught me to hip hinge by kneeling on the floor, putting a band in the crease of my hips and letting it pull them back. The upper body folds forward as the hips move backward. Kneeling takes the legs out of the movement and enables the glutes to work.
