Everything! I love that the workout is different every day and involves so many varying exercises so I never get bored! Plus, it is such an amazing workout for the same reasons! The coaches at San Clemente are great!!!
I always feel like I get a great workout. Classes are high energy and I may not be always be motivated to go to class but once I'm there I'm always glad I went. I get my cardio and strength training knocked out in under an hour. Working out is tough and it's nice to walk in to a gym where the instructors are fun, motivating and passionate about what they do.
Workouts are challenging. Trainers let you know what your mission is and do not allow any distractions from cell phones or other interruptions. The trainers maintain a good pace with the workout and you leave with the satisfaction of knowing it was very worthwhile.
