Thank you for providing this information. I've been getting hip pain when running so I'll see if I can incorporate and test the effects of a forefoot strike.
Every time I have had a leg-related running injury (knees, ankles, calfs, hip - you name it) the solution from the physio has always included doing squats.
Now if I feel a niggle coming somewhere I just do a bunch more squats throughout the day (whenever I remember really) and that usually solves it after a week or two. Nothing super strenuous - just like 10 to 15, perhaps 2 or 3 times a day
I have tried minimal shoes as well as super-spongy ones over the years, or trying to change heel strike Vs forefoot rtc and it seems it is only squats that make a difference!
