Frequently Asked Questions
How quickly can you change weight?
Turn the dial to the desired weight and lift — the unselected plates stay in the tray. Changes take under 3 seconds.
Are the plates secure?
Yes — the locking system uses steel pins that engage through each plate. Plates cannot shift or rattle during any exercise.
Bumper plates vs iron plates — which should I buy?
Bumper plates are rubber-coated and designed to be dropped during Olympic lifts. Iron plates are more compact and preferred for powerlifting and general strength training.
How should I store barbells?
Always store barbells vertically in a barbell holder or horizontally on a rack. Never lean barbells against a wall — this can bend the shaft over time.
