Steel Club or Clubbells as they are often called, have been a training tool for thousands of years dating back to ancient Persia.
Warriors would train with a heavy club to develop strong shoulders and a powerful grip required for swinging heavy weapons in battle.
In recent years the club has made a comeback, especially with athletes that require superior circular shoulder strength, grip strength and rotational core strength.
The club is an offset-loaded weight-training tool, often called a leverage-challenge tool, that works similarly to a Kettlebell or Steel Mace. The bulk of the club’s weight is set at a distance from its handle, making it difficult to stabilize and control. Because of this design, the club lends itself to rotational movements better than perhaps any other piece of equipment
