I don't think it completely starts with your hands, but it can certainly help to work on your grip a little bit. Not only will it give you an awesome handshake (but don't overdo it and be that person) but it can also help you do more at the gym when you go to lift weights for the rest of your body.

So if you're looking to kickstart your strength training regimen how about trying one of these grips that Women's Health recommends? There's Therapy Putty, the CandoDigiflex, and the Thera-Band flexbar, so you can easily find something that sounds right for you. Personally the putty idea sounds good to me -- sort of strength training plus stress relief rolled into one.
