The Trainer/Mitt Work. It's always fun working with the trainers. I will do all the other rounds, but I always look forward to that. If we can get more hands on interaction, that would make our workouts that much more fun!
9round is a great full body cardio workout, in an easy amount of time (35-45 minutes per session- in and out the door). You build both strength & cardio, and it is fun/ challenges your brain too with learning about boxing and kickboxing fitness!
