TRIBE is a fantastic program. Each class is easily adjusted to meet the needs of each individual, so someone like me (who rarely exercised before, and hates the gym) isn't left struggling to keep up, but the more active tribe members are not held back. Every one of us works to our limits, all at the same time. With the very small class sizes you get personal attention to what you need, and a close group of friends to bond with. It's the perfect balance of personal trainer and workout group. As someone who has never been fond of exercise, I find myself looking forward to going each day, and I highly suggest others try it as well.
