I was recently watching a Shaw Strength video where Shaw was training with a Mike Bartos Power Keg. I was beyond surprised to see that these were listed for $877. I was also very impressed to see the breadth of offerings my Mike Bartos' Power Center. For the competitive athlete, it is surely worth the $10K+ you could drop on his website.
It also made me appreciate how strongman has gone from lift heavy, cheap things like old bear kegs, big rocks on the ground, loaded up wheelbarrows, cheap welded sleds, continue ad infinitum to the plethora of uniform, loadable implements that folks have at their disposal to train with.
