I started working out with a trainer two years ago this month. My greatest extravagance and one with which I’m still a little uncomfortable. The lady is a sadist and quite willing to keep me doing crunches until I’m making pathetic little whimpering noises. But I’ve never felt better. I’m still a scrawny, middle-aged white guy but after 35 years at 155 pounds (6 feet), I’ve gained ten pounds of muscle mass. I view all this as my best investment. I’ll be able to do 100 push-ups while waiting for the OATS bus.
