this is my second time reaching this point. I kind of rushed through MNPE1 the first time through and struggled with the straddle ups.
I finally decided to regress and spent about six months working my way through PE1 again.
Now i"m back where i was -- I think i have very tight hamstrings, hips and calves. I can't get my knees locked out on this exercise.
I don't think regressing back to PE1 is the answer to this problem. But aside from just stretching and stretching, what can I do? What do I do in the meantime while I work on my posterior chain mobility? continue doing poor versions of the straddle up?
Also, before you tell me to do the stretch series.. . i have them. I'm sorry I can't work another 2 hours into my weekly work out schedule! I run about 4 hours per week, practice Aikido 9 hours per week, and spend about 4.5 hours per week in the gym doing GST (and some other mobility based exercises).
