Back in Uni, When I was still track racing at the Elite level, my two cousins were playing varsity football. One a Defensive End, the other a Linebacker. They wanted to get into better shape in the offseason, but didn't wan't to run miles, or lose their reactions time. So we played Squash that winter. Soon enough we had about 10 starters from the team playing with us, and I ended up becoming their personal trainer in the off-season. Ever see 250+lb guys play Squash? It's like watching that Hippo Ballerina from Fantasia.
