Hi Future Colleagues! So this issue has been on my mind for some time now and I would appreciate your input as dental students. I lift weights regularly and was wondering if that may have some negative effect while trying to learn the manual dexterity of a dentist in pre-clinic and clinic. For those that may not be aware...lifting weights regularly causes your hands to be rough/calice up in certain areas of your palm and fingers. In addition, more than just the external effect of rougher skin...i'm concerned about the internal effects of regular lifting weights on your muscles and joints of the hand (ie. having to squeeze strenuously while holding bars, lifting weights, etc.). What are your thoughts on this issue? Do you think that I should change my lifting routine to incorporate more cardio workouts just to be easier on my hands? I appreciate all comments!!
