Thanks, you are responsible for turning me onto training 3x a week way back when T Nation was Testosterone. I am going to go back to the Waterbury Method. I am over 40, certainly have more mileage in 2 fake knees and 2 shoulder surgeries. Thanks for what you do

Here is a tip as you age, to save stress on your joints: do your parallel bar dips, with an overhand grip like you use on bench press. This to me seems a more joint friendly grip. It obviously involves getting a dipping frame welded up like that, but its worth it. I, m quite elderly now, and my joints are very pleased with it lol.

Great tips! What about volume per workout?
