“Under no circumstance should I skip a warm-up or cool down Don’t worry about the distance Walking breaks are good—in fact, they’re encouraged Soreness is normal, but listen to your body if you feel pain Strength training is not optional Don’t worry about form too much at the beginning If you feel yourself breathing heavy, slow down Find a training plan that works and try to stick to 80% of it Start slow (no problem there) and don’t rush Ask for help or hire a coach It’s the last one that stings.”
