THE ANSWER

This blog started with the question: How much exercise does it take to add a pound of muscle?

My answer is one hour of hard exercise can build one once of muscle.

My scale is telling me that if I exercise for a half hour per day I can add a pound of muscle in a month. This is on my schedule of alternating swimming, weight training, and aerobic exercise.

I've had back injuries, arthritis and lots of pain which literally hurts my exercise schedule. My diet has been variable so this is a tentative answer. I'm keeping an exercise log book and I'm weighing in and taking my measurements with my tape measure and body-fat scale on the first day of each month. I'll have more data this year and I hope a more definitive answer.
