That is awesome information. How would they be for several people to use for training? Getting, for example, four of them to allow many people to train with them in the same facility. I wouldn't think I'd want to change the weights during a workout, but maybe change them workout to workout...
Do you have a feel for how they would be for serious KB training? By that I mean the difference between a GS specific gym and your typical "all around" gym where KBs are just a small part of the overall picture.
Sheesh, does that last question make ANY sense???
Thank you for your first hand experience.
