I like these weights much, they've bought in 3.4 and 5 kilos. Above all, especially in the exercises that I do, I think it's great that they do not roll away. For functional training and when changing between floor and jumping exercises with weights, it's just important that can not roll the weights and they are ideal for this purpose. But I originally wanted to hex weights these here are well priced for the home studio a super alternative. I wonder though how long will keep the vinyl, so far I'm very impressed. The weights are certainly weighty and you can feel the weight in the arms and legs now there is no more and the summer can come excuses.
