REP® x PÉPIN™ FAST Series™ Adjustable Dumbbell Add-On Weight

The locking mechanism clicks in so cleanly that I forgot these were add-ons, not the original set. That extra 20 lbs makes my shoulder presses feel like a whole new exercise, and the plates sit snug without any wobble mid-rep.

The 20 lb jump is exactly what I needed to push past my current plateau without buying a whole new set. The locking mechanism clicks in securely, and I can swap it between dumbbells in under a minute.

The extra 20 lbs makes such a difference when I need to push past a plateau, and the connection to the base dumbbells feels rock-solid mid-set. I’ve been adding it to my heavier days for a few weeks now, and it’s totally changed how I plan my progressive overload.
