Overview
Polyfit's adjustable kettlebell combines 5, 8 and 12 lb settings into one compact unit by adding or removing weight plates, aimed at home strength and swing training for beginners through intermediate users.
It comes with a laminated workout guide for structuring sessions without a trainer. One owner questions whether the plastic locking mechanism will hold up long term, which is a fair caveat for a design that leans on plastic rather than solid cast iron.
- 5, 8 and 12 lb adjustable settings
- PE-coated non-slip handle
- Includes a laminated workout guide
- Compact, travel-friendly size
Who it's for
Works well for beginners or space-limited home exercisers who want three kettlebell weights without buying three kettlebells. Not the right fit for anyone whose training already calls for loads heavier than 12 lbs.
Pros and cons
- Three weight settings in one compact kettlebell
- Small enough to pack for travel
- PE-coated handle stays grippy when sweaty
- Tops out at 12 lbs, limiting long-term progression
- Plastic locking mechanism's durability is unproven long term
- Swapping weights takes some trial and error at first
Performance notes
Weight plates lock onto the handle to move between 5, 8 and 12 lbs, so the same unit covers three effective loads. The handle carries a PE outer layer intended to stay grippy rather than slick when hands sweat. A laminated workout guide ships with it to structure short sessions.
