Sport Yoga
Runners, hockey players and part-time athletes can benefit from sport yoga classes, which are geared to counterbalance the wear, tear and repetitive motion of sports.

Body benefits: The stretches and strengthening moves target commonly used muscles in sports, such as helping to improve the range of motion on slapshot-shooting hockey players, says Jacqueline Walters, vice-president of group fitness at Extreme Fitness in Toronto.

Next Wave Boot Camps
The newest wave of boot camp classes uses TRX Suspension Trainers (TRX Suspension Training boot camps) and boxing pads (in mixed martial arts boot camps).

Body benefits: You'll reap overall strengthening of muscles you use every day (such as those in your back when you lug groceries out of your car, says Walters) and get cardiovascular exercise.

Piloxing
This fusion class switches between the fast tempo of jab-and-duck boxing to the slower body-conditioning moves of Pilates.

Body benefits: While boxing is heavy on cardiovascular work, Pilates conditions, lengthens and strengthens muscles. The tempo change is also interval work, which torches calories to help you lose weight, adds Walters.
