You could drive right by this little sunny gym in Prior Lake, if you weren't looking for it. But this morning I was looking for it, because BODY ROX is the only gym in Minnesota that has group classes utilizing the TRX suspension system. Straps with hand and foot holds on the ends hung from the ceiling. Those two straps and our own body weight were all we needed for a challenging, fun workout in one hour. "What is so incredible about TRX Suspension Training is that it is functional, powerful and fun," says Laurie Bushlack, co-owner of BODY ROX and my TRX teacher today. "We hear so much about functional fitness training these days where the focus is on training the movement , not isolating a muscle group.  TRX falls into that camp along with Kettlebell.  Every muscle fiber is recruited throughout the movements, resulting in overall body training.  The sheer simplicity and effectiveness of the TRX makes it a very powerful tool in our fitness and performance training arsenal. At just a couple of pounds it can be taken anywhere requiring just seconds to adjust and modify to fit the individual user who can be weekend warriors to professional atheletes alike. For the fun factor you can't beat being suspended and the kid in all of us that awakens when we get to do any swinging movements." It was well-worth the drive, which was shorter than I expected -- it took about 20 minutes to get there from South Minneapolis.
