I have been training with free weights for more than 25 years and am utterly astonished how weak and inflexible I am after reviewing F1.
I can do fairly heavy squats extending all the way to the bottom of the movement. What shocked me was that I am completely unable to do 1 rep of SLS/PE1.
The problem seems to be transitioning from the forward roll to my feet. I would be fine if I could get my feet under my arse and start the movement.
On the way down, I can get to the point where my hamstrings contact my calves and then there seems to be no further ROM. I end up just free falling about 2-3 inches.
Any thoughts?
