I bought the groupon for Monkey Bar Gym and I was extremely nervous (as I am not a particularly fit person), and now I am definitely going to get a membership.
When you first sign up they require you to come in for an initial consultation. They will show you around and give you information about how the classes work and what to expect etc. This is a great time to ask any questions you may have and learn how the facility runs so you don't feel so lost on the first day. The trainers recommend a plant-strong diet and encourage all participants to log their workouts. I had my initial consultation with Raquel. She was amazingly helpful, and encouraging. It was nice to know one of the instructors before I had even taken a class!
They post the daily workout on a whiteboard so you can check it out before class starts. They also have a binder that has all the workouts for the month, if you like to look further ahead. The workouts change all the time so you're never bored. Monkey Bar does a wonderful job of explaining/modeling how to do each exercise. They make it a point to go over every exercise you will be doing before participants begin the workout. The whiteboard also has a section that is divided into "stability" "strength" and "power". Here they have suggestions for modifications/challenges for participants who want to tailor their workout. The trainers are always helpful when it comes to finding an alternate exercise.
The trainers and members at Monkey Bar are very friendly. They ask you to get with a partner for some exercises and I have had no trouble finding a partner and striking up a friendly conversation with them. Members often say encouraging things to one-another during the workouts as well. One day after the workout I was getting a drink and a man (who I believe is an owner, or at least another trainer I hadn't met) asked me if I had recently joined. I told him yes and he enthusiastically welcomed me.
Overall, Monkey Bar is great. The workouts can be very intense but I always feel invigorated afterward. Great experience! :)
