The Wildman DeltΔ 40 Adjustable Kettlebell is the first adjustable kettlebell engineered for true long-term strength progression. Built in collaboration with Mark Wildman, the DeltΔ adjusts from 14 to 40 kilos (30 to 88 pounds) with precision .25 kilo (.55 lb) micro-loading, giving you the ability to train the way strength is actually built: one deliberate step at a time ( a total of 104 settings).
If you follow Wildman programming or you want the most mathematically correct kettlebell progression system ever created, this bell is your new foundation.
No clutter. No plate trees. No growing out of your equipment.
Just clean, measurable, scalable strength.

Rubber Coated vs Steel Clubs
Our rubber-coated steel clubs are built for serious training without the stress of damaging your floors. Whether you’re in an apartment, training barefoot, or swinging over tile, the protective coating reduces impact, dampens noise, and keeps your space safe—so you can focus on getting stronger, not fixing dents.
