Cortex Strongman Sandbag

What a training sandbag is

A sandbag is a filled, multi-handle bag for odd-object strength and conditioning — cleans, carries, over-shoulder throws, and loaded squats. The shifting fill forces stabilizers to work in a way fixed implements don’t, and the soft load is forgiving to drop. Durability lives in the outer shell (1000D Cordura is the standard) and the handle count/placement; most bags use inner filler bags so one shell covers a range of weights.
