Shoulder Boulder/Chest Fly Attachment

Great solution to a common problem.

The Shoulder Boulder is the perfect solution to the common issue that we encounter while doing dumbbell lateral raises... there's no resistance at the bottom of the movement. This attachment solves that problem and it works exactly as described. Plus there are multiple different adjustments possible to set this up to be the perfect fit for whatever you are trying to do. The packaging was excellent and the assembly was quick with very easy to follow instructions. This is my second purchase from BOS and I couldn't be happier so far with their equipment.

This a good product but a bit overpriced. Fits my equipment perfectly and easy to assemble.

Works great

Works how’d expect. Helps isolate the shoulder and promotes proper form with movements
