Today, fitness is not just about having fun but being around like-minded, supportive individuals too. And who better to work out with than your friends? Recent reports suggest there is an emerging trend, in the US at least, for fitness parties, where during birthday and other celebratory events you include some type of enjoyable working out session, where everyone can join in.
