Author's Note: What's happening when you get a second wind?

If and when your second wind does kick in, don't waste it. You'll feel its benefits as long as you continue to exercise that muscle or muscle group, but it comes with a caveat: Don't stop. A brief pause isn't a worry, but you'll lose it after about 30 minutes of non-intensive physical activity.
