Aerobic and fitness mats

a thicker mat forgives a hard floor during lying exercises, but it is unstable for standing exercises and your ankles have to work harder. For strength training and aerobics, therefore, go for a medium thickness, and a thicker one for kneeling exercises. The surface should be non-slip even when you sweat, otherwise you will spend half your workout sliding around. After exercising, wipe the mat and let it dry unrolled; a rolled-up damp mat will start to develop an odour within a few days.
