It goes without saying that you can use dumbbells to do strength training at home or your local gym. Most of us have seen lots of ordinary dumbbells in the past. Brain Dumbbells look quite unique though. These hand-cast iron dumbbells weigh 16 lbs each. They are durable and tough.
Steve Maxon and his team at Max-Cast have brain bookends available too. These are not cheap but you are paying for the amount of time and effort it takes to make them.
