Solid gympin, would recommend

It’s a pretty solid piece of equipment, to this point it hasn’t shown any major flaws, the only small flaws are that the pin itself does bend a little when under heavy load for a long time but not enough to be a problem and that the Kingpin isn’t as long as I hoped. In general I’d say it’s a good tool for overloading gym machines but it’s price might be a little too steep. In conclusion, I would recommend it for people who are willing to pay the high price.

Am now able to add more weight for chest press machine(the only machine that has ever targeted my chest out of anything) and therefore increase chest size. This was an incredible invention.

Absolutely love my kingpin it’s really pushed me to new heights by allowing me to add way more weight to the stack
