When performing SL/PE1, should I contract my posterior chain as hard as I can to get every drop out of my current ROM as I can?
Or is it better to hold a sub-maximal contraction and build ROM over time?
At max contraction and current max ROM, 12s is darn near everything I've got. But I can hold a slightly less ROM with a sub-max contraction and hold it longer.
Whats the best way to proceed?
Your experience?
Thanks
