I'm finding that my grip is failing before my other muscles on a few exercises (I'm almost 52, and certainly not the strongest guy in the gym). I'm having issues with shrugs (100 pound dumbbells) and lat pulldowns (doing about 175 on an unpadded bar)--these are both the maximum I lift with these exercises. I'm thinking about getting either straps or hooks to help with these. My day job is surgery, so I don't want to over-stress my hands. I normally wear weightlifting gloves, but they don't really help the grip issue with a few select exercises. Any thoughts/suggestions/product recommendations?
