For sure! Also should mention that I see an amplified effect of this stuff when I do it as a warmup for lifting. Really gets stuff aligned and I feel better in my lifts and sore in the "right" places afterwards (squats actually do make your glute meds sore, never would have guessed!).
Not to belabor the point, but I wanted to follow up with a better explanation of what's going on.
The general idea is that passive range of motion isn't nearly as important for joint health as active ROM. I think this makes sense, especially for athletes -- you have to get used to generating force in awkward positions so your body doesn't break if you end up in that position while skiing/climbing/etc.
There are two concepts that I find super powerful and let you design exercises for pretty much any joint:
1. move the joint through it's full active range of motion under tension (isometric contraction). I like to do 20% tension for 2 reps forwards and 2 reps backwards and then 80% tension for 2 reps forwards and 2 reps backwards. That's 1 set and I do 2-4 sets. This is what that first video in my last post showed for the hip, but you can do that with the whole leg (similar to side lying leg lifts, but you make big circles), ankle, shoulders, etc. Just ensure there's no pain/clicking/ pinching in the joint when you do it -- if there is, back off on the ranges you're using.
2. take the joint to it's passive end range and then generate tension in both direction (towards and against the stretch) via isometric contraction. (This is what the second video in my last post demonstrated.) This similar to classic PT "contract relax" approach to stretching, except you also contract the
opposing muscles as well. A favorite example is the classic adductor stretch*. It's typical to contract by pushing the leg into the ground and then sinking deeper into the stretch. But if I do the opposite and try to lift my foot up off the ground, my glutes fire like crazy and cramp up. It's such a simple concept, but I never thought to train my glutes to activate while my hip was in full abduction.
You can take these two concepts and apply them to any joint. Pretty crazy stuff.
