Need suggestions for non-slip workout mat(s)

My workout room has shitty linoleum tiles that are slippery before you even sweat on them. Once a few drops of sweat hit the floor, I want to burn the fricking room down it's so aggravating to try to workout in there.

I'm looking for some good heavy duty non-slip interlocking mats like you see in gyms. I'm google shopping, but I can't tell the cheap foam ones from the good heavy rubber ones that I can drop weights on.

Thanks.
