Blast Your Core, Shoulders and Forearms With This Brutal Kettlebell Challenge

This challenging kettlebell exercise builds massive shoulders and powerful grip strength.

Bottoms-up training is simple: Flip the kettlebell upside down so the heavy section sits directly above the handle. This has several benefits, including improved strength, size, grip strength, mental focus and posture.

I often challenge my athletes to hold two kettlebells in the bottoms-up position when kneeling on one knee for a specified time. It may look easy, but give it a try and I guarantee your opinion will quickly change.

In addition to the strength benefits, this tests an athlete's resiliency. They can often go for far longer than they think. They simply need to learn to crush the kettlebell with their hands and fight through fatigue. This exercise also helps to clean up poor exercise techniques, activates the muscles that support the shoulder, and of course, hammers the grip, which is essential for successful lifting and for your sport.
