The core home gym range
Eight matched pairs from 5 to 40 lb in 5 lb increments, the core range a home gym gets built on. Same PRx rubber hex construction throughout, six sided heads that protect the floor and stay put, and chrome plated knurled handles, delivered as one set instead of eight separate purchases.
Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. Every PRx free weight on our site is the same gear PRx sells directly, fulfilled and shipped to your door by PRx itself.
One Order, Whole Range
Pairs of 5, 10, 15, 20, 25, 30, 35, and 40 lb arrive together. No cross checking handle feel or finish between brands, every pair matches.
Sized for the Alpha 8-Tier
Eight pairs, eight tiers. This set is the exact spread the Synergy Alpha 8-Tier Vertical Rack is engineered around, one pair per tier on about 1.85 square feet.
Floor Friendly Rubber
Rubber coated heads take the sting out of every set you put down. They are quieter than bare iron and far gentler on garage concrete and gym flooring.
A Grip That Works
Slightly arched, chrome plated, knurled handles follow the natural line of your palm. Handle diameter is 25mm through 12 lb and 34mm from 15 lb up, with a 5 inch grip length.
Genuine PRx, Shipped Direct
Synergy is a PRx Performance retail partner. Your order is fulfilled and shipped to your door by PRx itself, the exact same gear PRx sells on its own site.
Room to Grow
When pressing weights pass 40 lb, single PRx hex pairs run all the way to 100 lb, in the same construction, so the set never becomes a dead end.
