I was inspired by Marta, who just signed up to have her own personal trainer to ask what ya'll thought of:
Kinesis is a functional fitness strength training system done in small group sessions. It involves integrated movements of balance, core strength and burns 30% more calories than traditional equipment training. Thirty minute sessions include a circuit of 5 stations.
Yeah, it costs extra, but it sounds cool. The people I know who tried it are totally into it....so readers, tell me what you think!
