ABOUT PHOENIX
CROSSFIT SARNIA
FITNESS FOR EVERYONE.
The needs of an Olympic athlete and our grandparents differ by degree, not kind. By that, we mean CrossFit works for anyone because the functional movements we train are essential to improving fitness and maintaining functional independence. For example, on a deadlift day, one athlete may move a barbell weighing 400 pounds while the other moves a broomstick. With appropriate scaling, an athlete will make significant fitness gains by working at their relative level of physical and psychological tolerance.
