I actually purchased this for my senior dogs. I have several sizes throughout my house. I needed them for their traction and non-slip capacity. I also needed something easy to clean (area rugs were no longer cutting it with senior dog accidents). I flipped this one over and used the bottom side on top, just because it seemed a bit easier to wipe down. It is quite comfortable to walk on, my dogs have no issue getting up from them and easy to clean! Good traction, not slippery at all. I can't speak to actually working out on this, but I would imagine it would be quite comfortable.I use this mat almost every day for my workouts. It's the perfect thickness for stretching, yoga, bodyweight and band workouts. Would not reccommend for use with weights because they'll tear it up. It's wide and grippy enough for me to do exercises where a regular yoga mat would not do, for example: wide step-climbers, lateral walking pushups, jumping lunges, etc. It's only 8mm (about 5/8ths) thick so keep that in mind.Updated: after a few months the product started to disintegrate. It sheds tons of crumbs after each use. Not the best quality.I ordered the 6*4 version in Onyx black for my home gym. I do strength workouts and cardio - always with my shoes on. When my knees/elbows are on the mat I need another yoga mat or a towel, as the Goplus mat is not soft enough. It is very heavy (I think it is at least 8 kg), but that's good for a home gym. It does not slip and can be rolled and put aside. It served my purpose, but I would not recommend it for yoga/pilates unless you put another mat on it. Excellent for a home gymGreat product!!! Enough space for me to work out.Works as intended. Has a bit of odor at first but it goes away after a while when rolled out.Belle grandeur pour faire exercice et bonne épaisseur
