Skull Kettlebell
Buy Now · $84.37The Skull Kettlebell is Yes4All’s novelty take on a fixed-weight cast iron kettlebell: a single US-patented casting shaped like a skull, sold as a 25 lb piece meant to double as a training tool and a decor item. It shares its parent line’s basic construction – solid cast iron body, black powder-coat finish, a wide handle sized for two-handed swings as well as one-handed work, and a flat-ground base intended for floor-based moves like push-ups and renegade rows. GymRadar’s small sample of owners (3 reviews, 4.11/5 average) likes the design and price but is split on execution: two of three call out rough, uneven casting and an unstable base, the same soft spot that shows up elsewhere in Yes4All’s cast iron line. Treat this as a fun conversation-piece bell rather than a precision training tool, and expect the finish and casting to trail purpose-built competition or premium cast iron bells.

What is a Kettlebell?
What kettlebells are
A kettlebell is a cast-iron (or steel) ball with a handle, built for swings, cleans, snatches, presses, and carries — ballistic, full-body work a dumbbell doesn’t do as well. One or two bells cover a lot of conditioning and strength.
What actually matters
- Cast iron vs. competition. One-piece cast iron is the durable, affordable default. Competition (“comp”) bells are steel and share the SAME dimensions across every weight, so your technique doesn’t change as you go heavier — worth it for dedicated technique/girevoy work.
- Handle width & finish. Handle diameter and width decide grip comfort for two-hand swings vs. cleans; a smooth handle takes chalk well and won’t tear hands the way an overly rough powder coat can.
- Coating. Powder coat grips well but varies in roughness; e-coat is smooth and rust-resistant; bare handles need chalk.
- Single vs. adjustable. An adjustable kettlebell saves space and money if you want a range, but adds bulk and can feel less balanced than a fixed bell.
- What to buy first. Common starting points are ~16 kg (35 lb) for many men and ~8-12 kg for many women — then add a heavier and a lighter bell as you progress.
Who it’s for
Anyone who wants conditioning, posterior-chain power, and loaded carries without a rack. Start with one well-sized cast-iron bell; add weights or a competition set as your training demands.

The Skull Kettlebell is Yes4All’s novelty spin on a standard fixed-weight cast iron bell: a US-patented skull-shaped casting meant to double as both a training tool and decor. Owners consistently praise the design and price (GymRadar’s Value sub-score is a perfect 5.00/5), but the small available sample is split on execution — two of three reviewers call out rough, uneven casting and an unstable flat bottom, the same weak spot that shows up across Yes4All’s cast iron line. Build quality is the weakest dimension here; value for a conversation-piece kettlebell is the standout.
- +Value: rated 5.00/5 on GymRadar — reviewers feel the skull design is a fair trade at this price versus a plain cast iron bell
- +Functionality: wide, smooth handle sized for two-handed swings as well as one-handed presses/snatches, per Yes4All's own spec copy
- +Versatility: flat-ground base is intended to support push-ups and renegade rows, not just swings
- +Functionality: novelty factor is real — the one 5-star reviewer bought it specifically to stand out ('one bad dude') and would recommend it for that reason
- −Build quality: 2 of 3 GymRadar reviewers report rough, uneven casting ('casting is no clean')
- −Build quality: one reviewer specifically flags an unstable flat bottom, undermining the base-stability claim
- −Durability: no independent long-term data — all signal is 3 short owner reviews, no editorial teardown or stress test
- −Functionality: fixed single weight per unit (25 lbs), so progression requires buying additional bells rather than adjusting one
