This is the best GroupOn purchase I have ever made. Many have said the booking process is a pain, but it really isn't if you follow the specific instructions provided. I have never had any issues with responses to emails. All of my emails have been responded to within 24 hours in a professional manner.
This is a great supplement to my regular workouts and has reduced my upper back pain. The cost of the classes is a little high, but is signifcantly cheaper than paying a chiropractor or going back to physical therapy. The classes are fun and the instructors are extremely helpful. I am never disappointed!
