Our Torque Magnetic Weight Stack Adder Pin allows you to train at your pace with the exact amount of added weight you need to improve your fitness. Attach a pair of pins to our F9 Fold-Away Functional Trainer weight stacks for an extra 2.5 lbs. or to any other cable stack. Add to your PowerBlock® Dumbbells to insure you're still building muscle in between adjustments or even stick onto a lifting rack to hold your change plates. No matter the use, this pin is durable and sophisticated. Continue to add weight incrementally to a variety of training equipment to push your workouts and reach a new PR, even if it's 2.5 pounds at a time. Sometimes it's the small things that make a big difference - Don't Quit. Ever.
