The Exterra MP-3000 Group Exercise floor is a true Multi-Purpose floor system that is appropriate for Pilates, group cycling, mind-body exercises and traditional low-impact aerobics. It utilizes the same tongue and groove flooring boards as the Exterra Classic system, and the Silver Spring installation method, but the system is underlain by a 3/8? foam padding layer. While this thinner foam does somewhat reduce the shock absorption properties of the flooring, the system is still appropriate for most activities except high impact aerobic exercise.
