A bit of background first, I've been doing the GB Ultimate for about 3 weeks now with the suggested workout schedule. I started GB in the hope that it will fix a niggling injury. I've had some lower back pain and stiffness for months, probably due to squatting through pain (silly, I know). I've seen 4 physios about it. Some think it's a bulging disk, some don't, but none of them think its a big deal and that I just need to build a stronger core and glutes.
While doing the workouts I've noticed that I can get back pain doing stiff leg windmills, particularly if I can't focus on an aggressive anterior pelvic tilt. My mobility in this exercise is very poor. There are several other exercises where my mobility seems especially poor - pancake, pancake shoulder, pike, and vertical lunge (due to quads).
I feel like maybe I should be doing these exercises and stretches more, but in one of the stretching routines, I heard Coach Sommer say that doing it once a week might slow down progress. I don't want to over stretch but I feel like I need to address these areas. Is there any way I can address my problematic areas by, say, shorter duration stretches a few times a week?
Cheers,
Jared
