PowerBlock Sport Expandable 5 to 50lbs (base set)

Expandable
‘EXP’ models start at 50 lbs. per dumbbell and can then be expanded with 2 kits. A kit adds 20 pounds to each dumbbell, so a Stage 2 is 50- 70lbs. and Stage 3 is 70-90lbs. This is a great option for anyone who wants their set to grow with them.
Sold in pairs.
