A nice thick shock-absorbing mat means the world of difference between just a mere bruise or a broken limb. Suppose you are looking for a mat for yoga, floor exercises, or stretching. A 2/5 inch padded mat will be of excellent service to you: since it will not only give you a comfortable (shock-absorbed) solid place to work out on, but it’s pretty portable as well. Otherwise, for jumping, burpees, and such intensive exercises, a firmer foam of about 1-2inches thickness will be able to withstand the vibrations and shock produced.
