When you are closing the 250lbs for reps you will have to be very careful when shaking people's hand! If you can close the 250lbs once your hand strength is well beyond the average athlete. Usually only athletes with a hardcore grip training regimen and people who do heavy work with their hands can close the the 250lbs on their first attempt. Just because you have lifted weights for a few years don't assume that you will be able to close the 250lbs. It's much harder than it looks!
