How can a weekend warrior avoid overdoing it?
Your body tells you that you have trained too hard: you have cramping calves, an aching back, or a pulled muscle. How can you prevent further aches and pains?
The first precaution is to warm up. You may not have done it at age 20, but it may be essential at 50 or 60. Also, hydrate. Drinking water may be better than sports drinks (which tend to have high-fructose corn syrup or other unnecessary added sugars).
