I like that you are working out in a group which helps motivate you but it is your own workout at the same time. You can push yourself or not. I like when the coaches say that it is a judgement free zone- don't worry about what your neighbour is doing. I like that it is a quick 55 minute intense workout and I can get on with my day. I would never push myself on my own or if I just went to the gym and did the same type of routines.
It short and discipline. Friendly environment and not intimidating.
The only concern is the showers!!!! Not enough for the people that have to go to work & getting ready for the time of 20 min is not enough
