HG 250 "Professional" - When you are closing the HG 250 for reps, you will have to be very careful when shaking hands! If you can close the HG 250 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 HG 250 on their first attempt. Just because you have lifted weights for a few years, don't assume that you will be able to close a HG 250. It's much more challenging than it looks!
