I thought you might be interested in what my movement specialist said regarding my video updates after 9 weeks of corrective work.
"One thing I mentioned to him was how much less metabolically fatiguing I found doing front foot elevated split squat than previous weeks. It hit me like a ton of bricks when I read that part about ‘stiff tissue being fatiguing’. Of course, if a muscle cannot contract its full ROM, imagine how much energy it will require to generate enough force to do a movement with restricted ROM.
So, long supple muscles with strength across the full ROM will demand less energy and be less tiring for the body. This may seem obvious but it had never occurred to me yet I think it is critically important."
