Journey to Fitness: Stories of Progress, Challenges, and Triumphs.
Don’t feel like an idiot if you can barely stay on the treadmill for fifteen minutes at low speed the first day. It is not struggling on the first day or the thirtieth or sixtieth that’s going to work. It’s showing up every day and doing something. Do something every day for a week, and at week’s end you’ll be doing twenty minutes. Or thirty. Whatever. Push yourself a little. Don’t push yourself over the edge if you want to stay young. Before too long, you should get up to doing forty-five minutes a day of aerobic exercise.
