There’s a Certain Term Used For Heavy Kettlebells…
I have no idea who coined it, but the appropriately named monster kettlebell should only be used by serious lifters. While there is no set definition, it's assumed that any kettlebell weighing over 100 lbs. fits that description. Unless you're Hercules, exercises that require the kettlebell to be lifted overhead are near impossible. Typically, exercises with monster kettlebells include squats, rows, and deadlifts.
