This is the legendary inch dumbbell performance by Mark Henry. For those of you who are not familiar with the Thomas Inch DB, it weights about 173lbs. and has about a 2.5in. diameter handle. I have tried to pick one up off the floor and could not break the weight from floor contact....it would just roll to the side. Watch Mike play with this thing...the most impressive things is how he just picks it up, walks it over to the table, and sets it down!
