I think that you really need to enforce sticking to your numbered station. Some people want a specific treadmill and rower but when it comes to the floor, they do not go to their corect station. Another issue has been when the benches are out and we have to use TRX, if its a full class, you have to wait until the person next to you finishes on the bench to use your TRX, or vice versa. There is no space.
The workout incompasses different muscles and at the end of a just one hour you feel like you worked your butt off. lol
Majority of aventura group coaches are very knowledgeable and professional. Unfortunately there are still some who are not engaged in the workout and only tell the class what to do and never correct anyone's form or make sure the people are clear on what the exercise is.
