“These dumbbells are constructed using the best materials and the craftsmanship on these is unbelievable. Sure you pay more for Ironmaster but the product speaks for itself, it’s extremely well built and it lasts a lifetime. If you’re considering other dumbbells, pay the extra amount for these, it’s well worth the investment.” – Dario

Why Quick-Lock Dumbbell Set?

  1. Essential add-on
    In combination with a few dumbbells in the lighter range, an extra set of quick-lock handles simplified my workouts. Everything Ironmaster makes is QUALITY and is worth the price (IMO).
