At the city's only Super Slow facility, trainers take you through a series of weight training exercises at an extremely slow (10 seconds to lift and 10 seconds to lower) but fluid pace. Working the muscle almost to the point of failure will leave you shaking and trembling until it's impossible to lift the weight. This stimulates the muscles to become larger (not bulkier) and causes the metabolism to speed up. No music plays; sessions only last 30 minutes; there are no mirrors or grunting and facial distorting is discouraged—all things that would take your focus off the challenging task at hand. In addition to being a quick, intense workout that you only do once or twice a week, no other training or cardio is needed. "The intense workout stimulates all systems in the body," says Theresa Snyder, co-owner. "When you start with the leg press, working the largest area of muscles first, you're asking your body to work hard so it gets your heart rate going." Individual sessions cost $57, while package rates offer nominal discounts.
