The things I like best about the fantastic gym at Woodward West are their padded trench pits for bars.
Yes, “pits”.
They have two. One for men, one for women.
For spotting blind change, a trench pit is particularly useful. Y(ou can step across while the gymnast turns.)
Almost any same bar skill is better learned in a trench pit. I’m convinced that the elite coach there Don Eckert can teach anyone Tkachev on this set-up.
