Just bought a treadmill, elliptical, or stair climber and now in need of a heavy duty mat to protect your floor? The MAT366 from Impex Fitness is just what you are looking for. Measuring 3" wide by 6"6" long, this mat will accommodate most treadmills and other cardio machines on the market. The high impact polyfoam structure has a 1/4" thickness and is designed to withstand the weight of a high end exercise machine. The high density design also helps to reduce noise and vibrations that can be common with these styles of equipment.
