On average for a beginner at weight lifting?

On average for a beginner at weight lifting?
For a beginner? No time at all. This can easily be accomplished with the right plan and one bulking/cutting cycle. Loosely following my guidelines in the first half of 2005, I gained 8-lbs. of lean mass on Swolecat's SGX. Greater results can be had with more discipline than I applied to it, and at that point, I'd been lifting weights for almost two years.

So that would burn 500 calories extra, right?

Elaborate on your question, please.

Are you asking if 10-lbs. of muscle would burn an extra 500 kcal/day? If that is your question, there is no reliable corollary between calories burned per unit of muscle mass.
