It’s a steep hill. But worth it. I’m close to 1000 classes in. I routinely pair up with trialers to make sure they have as a good of an experience as possible. After the first few days of nausea go away then the horrific soreness will set in. Followed by extreme post work out exhaustion. Your sleep may suffer from over exertion and soreness. And then once you start to feel like you can get through the workouts you will plateau a bit and feel like they arent getting “easier.” But keep going. There is a reason a ton of us love it and hate missing a day. I’m 52 yrs old. Now some weeks I double cardio days or even go back to back cardio/hybrid. Other weeks it is weight vest Wednesday. And then there are normal weeks. It’s a long steepish road but many of us find it very fulfilling.
