Crossfit Flinders

Really friendly box! Great price for the really close attention you get from the coaches during the sessions and excellent programming by head coach Alex. They're happy to tailor the workout for your abilities and guide you to a higher level of fitness.
A little difficult to find at the university (behind the gymnasium, door next to the news bike parking, down the stairs in the basement), but definitely worth seeking out.
Lovely group of people who attend - making tough workouts a lot more fun.
