New Premium Design 

SMAI Xtreme Core Bag has a new premium design that features an improved overall construction to increase the life of your fitness gear. The core bag has been carefully constructed to be made of reinforced materials such as a pebble filling and strengthened inner and outer layers.

Featuring unique handles (one side has them running length ways, the other width ways) the SMAI Core Bag allows an array of dynamic, multi-plane movements with the option of a pronated or neutral grip depending on the exercises you wish to perform.

Filled with washed pebbles that are then housed within a lining bag they are tightly positioned in a central location. This ensures a balanced weight within the bag. The outer surface is then lined with an NBR rubber foam for a uniform and soft even appearance that ensures the pebbles cannot be felt when used.

The SMAI Core Bag is a dynamic piece of equipment that allows the teaching of correct form and technique for beginners in aspects of training such as:

    • Strongman (atlas stones, farmers walk, keg walk etc)
    • CrossFit when using them in WODs
    • and Kettlebell training

Not only can you incorporate the Core Bag into body weight movements, it is also an alternative to barbells, dumbbells and kettlebells. This is useful for outdoor training options or when performing multiple exercises, as this means you don’t have to mess around with changing through different pieces of equipment.
