My wife has trained with Dave for many years and had encouraged me to try him. I have a shoulder injury that I was certain would require surgery (when is it convenient to have surgery on your dominate arm and be in a sling for weeks?) so I thought I couldn't exercise. Dave and I just happened to be talking one day and I mentioned my injury. After testing my range of motion (Dave is a physiologist) he said he thought he could fix it?!? My first session, he had me attempt to do a shoulder exercise with a 1 pound weight and I physically couldn't force myself to do it. Fast forward one month of very specialized exercises and I could do the same exercise, pain free with 15 pound weights!!! I've now been working with Dave for several months and haven't looked this good in years! I couldn't be happier with Dave or my results!
