Good for running injury?

My sports dr provided me this site to look into. I've had a running injury for a year (strained muscle leading to unstable hips and SI joint leading to some major glute and entire chain imbalances). Would the Foundation 1 help to correct imbalances? I'm hesitant to spend the $ without input from runners.

I am a competitive runner and compete in events up to 50 miles on a yearly basis.  most of my running is in the 30k-50k distance.  Most runners are extremely tight in their hips.  What they call unstable hips is actually too tight hips, which pulls your SI out of alignment.  Most also have difficulty activating their glutes.  This is a circular problem that keeps compounding itself until injury occurs.  The cure is improved glute activation and better active hip ROM.  Both are accomplished in the foundations program.  If you are committed to putting in the time and disciplined to stick with it, you will see tremendous progress if your problems are as you suggest.  Runners don't do enough strength training, but the elite runners are starting to take notice and do more of this type of thing.  I would also recommend RDL's (Romanian DeadLifts) for runners.  This is very good at glute/ham activation, and active hip mobility.  For the cost of a single PT session you could have Foundation 1 which will last you months.  Good luck.

Along with the handstand mobility, I'd say that the F1 leg mobility is the absolute best bang for your buck in terms of injury prevention and rehab.

Thank you for the replies! I'm definitely going to try this. I want to get back to running injury free, so this sounds like it will help.
