Heavyweight Kettlestrap

Designed and manufactured in the USA, Spud Inc.’s Heavyweight Kettlestrap gives athletes a convenient new way to ramp up their kettlebell swings—with no actual kettlebells required. By loading the durable 16" nylon strap with standard Olympic plates, you can create an effective kettlebell alternative that enables customized, incremental weight changes from 5LB up to 175LB. The Heavyweight Kettlestrap fits in any gym bag and features a 6" long steel-core handle with a textured rubber coating for a firm grip. To add your desired weight, just slide the handle through the center of each plate (25LB plates work best) and let the resulting stack serve as your makeshift kettlebell. From cost-efficiency to portability to advanced training options, the Heavyweight Kettlestrap is a simple accessory that pays big dividends.

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.
