In it, Liederman makes the case that every man should be physically fit enough to save his own life in an emergency. He sets out five fitness benchmarks that indicate whether a man is up to this task. None require you to be able to bench press 500 pounds or have six pack abs. Rather, the benchmarks focus on having the strength and endurance to run, swim, or pull yourself to safety. If you're looking for a fitness goal, the five fitness benchmarks Liederman lists are a good place to start.
