Take body pump 2-3 times a week and see what happens. You will work hard. You will have fun. You will build lean muscle. You will burn calories bigtime. You will transform your body!
If you like being pushed in a workout and want to challenge yourself early in the morning, take Boot Camp with Anna Mondays and Wednesdays at 6:30 a.m. It'll make you work but it's awesome!
Get a fitwell pass and take all the classes you want for one price instead of paying per class. If you use it even just a couple times a week, it'll pay for itself soon.
