I would say when Gasper went out of his way to make me a West-Side BB template. For some reason it mixed in really well with what I was doing for MMA, plus any of the Gpp that I had to do for West-Side seemed to fall right into slots that crossed over with MMA.
Now there seems to be a West-Side BB for MMA Fighters that Joe Defranco just put together. It's not much different then the standard template, except there are a few more explosive lifts and a tad bit more mma/Strong man type core work. I tried it and don't like it, My success comes from me being stronger
so I stick with the current WSBB Template with MMA GPP on off days.
