Fitness Mat (10mm)

The ridges on this mat really do keep it from sliding around during floor exercises, which was my biggest worry with thick mats. The foam is dense enough that I don't feel the hard floor underneath even during core work.

Ten millimeters of foam sounds excessive until you try doing planks and bird dogs on a hardwood floor — my elbows and knees are finally thanking me. It's bulky to roll up and store, but the cushioning is worth the tradeoff.

The ridges actually hold my hands steady during plank, and the extra thickness makes lying on my back for stretches feel almost like a real mattress. It's firm enough to stay stable but soft where it counts.
