My powerlifting coach has suggested that switching to Sumo may decrease the loading on my back as the bar will be closer to my body. Currently he's asked me to keep with conventional to build up lower back strength though. He says my form is as good as any stubby guy's can be and he's pretty knowledgable...I think.
Stiff leggeds, romanian deadlifts, reverse hypers, GHR's, back extensions, and pull throughs all hurt. I could do leg curls, but wtf good is that going to do?
I think recovery is the real problem, but perhaps I've got some tight muscles causing the problem? I've started stretching my hip flexors, quads, and hams like a mofo.
I also take 3-6 grams of concentrated fish oils per day. i've not yet decided if I think Flameout is much different. I tend to do research before acting.
As far as ART, it think it is fantastic. It has helped tremendously with old nagging injuries. There is one caveat though. You have to find a good provider!!! It is like any other profession. There are those who are good and those who aren't so good (i.e., they suck). Ask the top guys in your area who they send thier clients to.
