As we left the gym after our first real workout in years, my husband and I both felt energized. "Let's make a commitment to do it three times a week," I said.

"Absolutely," my husband agreed, "three times at a minimum."

"And no whining," I said. "No excuses."

"No, we'll do it," he said enthusiastically, "you can count on it."

"And on my late night, we can just meet here at the gym."

"The gym?" my husband said, confused. "I thought we were talking about sex?"
