Usability at planet fitness
I originally purchased this to fit my leg extension. At plant fitness (Matrix Ultra Series Leg Extension) and i found out its actually not fitted to a 10m probably 8 and its too long for the cable stacks for overhead tricep ext or tricep pressdowns so I cant use it for that. Maybe in a year ill use it for the chest fly so ill still put it to use and it looks high quality it just sucks because i think ill need a 3 inch 10m pin and a 6 inch 8m pin so I can do leg ext and overhead tricep ext, its my fault for buying the wrong ones. Ill probably pick those up soon bc ima need more weight.

Great review here
I’m impressed with how easy it is to work with MGainz. I ordered the smaller pin and realized I needed the larger size. It was an easy and quick return process. I’m glad I have the gym pin.
