The PowerBlock Pro 100 EXP starts as a compact 5–40 lb adjustable dumbbell pair and is engineered to grow with your training. This is the Stage 1 base set: two dumbbells that adjust from 5 to 40 lbs each, then expand all the way to 100 lbs per hand by adding the Stage 2, 3, and 4 expansion kits (sold separately).

Weight changes happen in seconds. A magnetic selector pin drops into the stack and locks the plates you want, while included micro weights let you fine-tune the load in 2.5 lb to 5 lb steps — ideal for progressive overload and dialing in proper form. Color-coded rails line up with the handle chart so the selected weight is easy to read at a glance.

The Pro 100 EXP uses black urethane-coated plates for a quieter, more durable workout than bare steel, and ships with a knurled stainless steel handle for a secure, non-slip grip. Built for advanced lifters and trusted in training facilities worldwide, it pairs with the PowerBlock ecosystem of attachments to convert into an adjustable barbell or kettlebell.

Sold as a pair and backed by a 5-year limited warranty for residential use. Buy the base today and add expansion stages as your strength climbs — one system can replace an entire rack of fixed dumbbells.
