Our Tough Mats are durable enough for weight lifting. Depending on the amount of weight and the type of weights you are using will determine if this mat is a good fit. Our Tough Mats are fine to use with any type of plate, as the full weight of the plat is diffused when dropped on the floor. In regards to dumbbells, we recommend using dumbbells that are around 50 lbs or less on this mat. Since this is rubber is a little thin, there is potential for subfloor damage to occur. If you are looking to use heavier weights, we would recommend using one of our thicker mats.
