Muscle growth is a response to stress. You tax your muscles and your body produces more muscle mass to make the same work easier next time; in the same way that your skin darkens when you've been in the sun, so that the next time you're in the sun, it's effects are lessened. Get it?

So, working those muscles to exhaustion will tell your body to make maximum muscle. The fastest way to do this is to lift really heavy weight for a short period of time. Pete Sisco ran a study that showed whether or not you lifted 400 lbs over 10 seconds, 800 lbs over 5 seconds, or 1000 lbs for 1 second, you do the same amount of work, and the muscles respond by requiring the same amount of growth. You still need to train those gains to work for long periods of time at lighter weight - hence the training with the heavy club.

A new highlight: Golfing the home course on Christmas Day.

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.
