When fitness people start getting serious about strength training, conditioning, or functional workouts, one tool keeps showing up everywhere — the Kettlebell. It’s simple, powerful, and brutally effective. From swings and squats to carries and presses, a good kettlebell becomes part of your weekly routine. And that’s when the real question begins: Should you go for a solid metal option like the PROIRON Cast Iron Kettlebell, or choose something lighter-feeling and coated like the Protoner Polyvinyl Chloride Kettlebell?
Both kettlebells are popular among people who train at home or in basic gym setups. Both promise durability. Both help build strength. But they are not the same experience in your hands — and choosing the right one can make your workouts smoother, safer, and more enjoyable.
According to the American Council on Exercise (ACE), kettlebell workouts can burn up to 20 calories per minute during intense sessions, which is comparable to running a 6-minute mile — meaning these compact weights pack serious power into short workouts (Source: ACE Study — “Kettlebell Training Provides Powerful Workout”).
So let’s break down both options in a real-world way for fitness people who actually train — not just look at gear online.
1) PROIRON Cast Iron Kettlebell – An Overview
The PROIRON Cast Iron Kettlebell is a true old-school strength tool. It’s made from single-piece cast iron, meaning there are no joints, attachments, or outer shells. This matters because single-mold construction usually means better durability over years of training. The flat base helps the kettlebell sit firmly on the floor, which is useful for moves like renegade rows or kettlebell push-ups.
This kettlebell feels like something you’d find in a strength gym — raw, solid, and stable.

2) Protoner Polyvinyl Chloride Kettlebell – An Overview
The Protoner Polyvinyl Chloride (PVC) Kettlebell is built differently. Instead of being solid bare metal on the surface, it has a PVC outer shell, usually covering a weighted core. This coating gives it a smoother, softer exterior feel that’s generally more comfortable for beginners or casual home users.
The PVC coating also protects floors better than raw iron — a big deal if you train on tiles, wood, or marble.
