Book Preview: 

#1 To make muscles, such as your biceps, stronger, you must find the Goldilocks weight: an amount you can barely manage, which will leave you exhausted but not injured by the time you’ve finished your workout.

#2 The cycle of stress and rest is referred to as periodization in the world of exercise science. It involves isolating a muscle or capability you want to grow, stressing it, and then resting and recovering to allow for adaptation to occur.

#3 Deena Kastor is the most famous American woman runner, and she’s won an Olympic bronze medal in the marathon. She holds the American marathon record, having covered the 26. 2 miles in just 2 hours and 19 minutes.

#4 Kastor’s secret is understanding how much stress she can handle and how much rest she requires. She has mastered the inputs, and understands how much stress she can tolerate and how much rest she requires. Thus, the output – a lifetime of growth and excellence – isn’t surprising.
