In regards to the following quote from Jeff Gonzales of Trident Concepts:
"Keep your shoulders active, pull back on the shoulder blades. Don't let them round and roll forward"

I am curious to hear more about this from folks who have trained with Mr. Gonzales. My interpretation may be different than what is intended. I have been exploring this, and the Leatham calf tension concept as mentioned by SLG, in over the past several sessions.
