“Do pushups, so if you fall down you can get up fast, do pullups, so you can pull yourself over a fence if need be, do sit ups, so you can get out of bed in a hurry, do squats, so you can jump up with power, do calf raises, so you can climb hills like a young roe, and run, run so you can out pace the enemy, and fast while the food is plenteous so you'll be prepared when the food is none.”
