The whole block is large, easy to move and store, with strong anti-slip grip and will not move after strenuous exercise. Using high-density PVC material, the thickness is 7mm, which is just right, neither thick nor soft, and has good seismic stability. Do not sprain your ankle when running and jumping, and protect your joints and floor. It is very suitable for doing exercises such as T25, P90X, M30X and Burpee of Insanity with the video.
