The level of fitness matching the level of fun is often a difficult thing to find, but Block21 accomplishes this x100. Sally is so fun, encouraging and pushes everyone to a healthy degree. All people - dancers and non-dancers - will truly enjoy this class because you push yourself to your own limit! Block21 provides me life balance and physical fitness without having to join a sterile gym or attend bootcamps. Highly recommend to anyone wanting to have fun and get a good workout in great company. At the end of the day, its the best Saturday night out on the dance floor without the hangover!
