Hey guys. I've been doing the suggested workout routine of the GB ultimate course and I'm just wanting to check my form. More background on my situation in the link below.
I've attached two variations of the standing Pike and one of the narrow hurdler. I wondering if I should be keeping my back straight to reduce strain on the lower back. I vaguely remember hearing something about that in one of the videos.
Also, since my hamstring flexibility is so bad, is there anything that I can do on the days when I don't do the front split stretch routine to improve my progress?
Cheers
Jared
