HOTWORX - Cartersville, GA - Cartersville Anna Patrick: Be prepared to get your sweat on! The saunas make me burn so many more calories than I would in a normal workout. I get a great mix of strength training and cardio. I’ve never been a big weight lifting person so the isometric workouts have been great for my muscle building. I like the privacy of the saunas as well. I can truly disconnect and focus on my workout without having to worry about wandering eyes.
