Frequently Asked Questions

What does a weight-reduction pin do?
It lets you adjust the load on a weight stack more precisely than the standard increments, so you can progress in smaller, smarter steps.

Which size should I choose?
Check the diameter of your machine's selector hole — most use either 7.8mm or 9.5mm. Measure if you're unsure.

Are they durable?
Yes — the aluminum-alloy construction is built to handle repeated heavy use without bending.
