Brutal, in the best way. I was worried that I wouldn’t feel it in my legs because of not using any weights, but I’ve been sore for three days now. It definitely works. The only reason this is getting 4 and not 5 starts is because there isn't anything for biceps and back, so it’s not a full body deck. I understand that it’s designed for anywhere, and push exercises and legs and core can be done anywhere with this deck, just wish there was a deck for pull movements (back and bi’s).
