The workouts are never the same, I love the fast pace, an hour flies by. I am definitely more pushed than I would be if I worked out by myself. The coaches are knowledgeable and Great. I find the group setting motivates me
I love the variety! Group classes usually bore me, but OTF was an intense workout that was always different and kept me engaged. Plus - since I'm competitive - being able to see my stats made me push myself much harder than I would have otherwise.
I just show up and the trainer has the workouts planned and pushes me through! I like that it's comprehensive and well rounded but I don't have to think about the planning. The science behind heart rate monitor training is wonderful and definitely not something I would manage for myself.
