Found an interesting link with pictures over at the Nugg Doctor of Steve Hess working out Arron Afflalo, Chauncey Billups, Chris Andersen, and Nene.
You can give it a look here.
Some pretty interesting methods of training ... a climbing wall, running the stairs at Red Rocks, traditional treadmill, and pool workouts. I'm thinking Nene may work out in a pool to help with his joints and to save his knees a bit. There is nothing more awkward that sweating in a swimming pool ... very odd feeling (back in my football days!)
