Established in 2011, Workout Sandbags was set up by a retired Texan teacher/coach. After using a duffel-bag style sandbag for training, he took a year to design his own. The result is a giant beanbag shape which provides more instability – making the trainee need to work harder. They also have internal handles for better grip and are made from thicker, stronger 1050D ballistic nylon that won’t leak. They are sewn at their onsite shop, guaranteeing quality control.
