Yes I understand not wanting to get locked in – I have felt the same way with a lot of these that require lock-in and credit card info right up front without getting a chance to try. http://www.fitsw.com/ is very good about this as they make it free with no credit card to sign up. It does seem more tailored to individual trainers and smaller gyms rather than being as polished as something like mindbody. Don’t get me wrong it is still great and has excellent ways to track progress on your client’s fitness and does a great job at creating and recording workout plans and diet plans. But if your looking for something for a multilocation gym mindbody.com is probably the way to go.
