short stride length, flexibility problem?

Your upper body is rigid. There is crap movement around the shoulders, they are up rather than down, and your upper back is not moving smoothly. Mobility work and stretching can work–I never said it wasn’t good. I said simply looking at a number (as in, peak ROM you can reach in a given stretch) isn’t a good idea nor is it a good indicator of tissue quality, which is more important and probably more related to your hip tightness. Further, people can and often do cheat on stretches, which you are likely doing as well, which is going to create a false negative.

kk, so your basic reccomendation is more mobility work?
and upper body movement? same thing?
