Excerpt from : Valkyries, Valhalla, and The Way of the Samurai (“Soft” Standards, and the Philosophy of Stoicism) | Mountain Guerrilla - John Mosby Ultimately, if you want to do PT to improve yourself, it’s not particularly difficult. Lift more today than you lifted yesterday, and lift more tomorrow than you can lift today. Run or ruck further and faster today than you did yesterday, and run or ruck further and faster tomorrow than you do today. Any strength and conditioning specialist or personal trainer will, of course, tell you that this is a gross oversimplification. You have to factor in all the variables: nutrition, rest and recovery, etc. Bullshit. If you walked out in your front yard right now, and picked up a 45-lb Olympic barbell off the ground and pressed it all the way over your head, and did that five times, then repeated that—and nothing else—every single day, rain, shine, sleet, or snow, adding five pounds every day, in a month, you would be fitter than you are today. If you walk outside now, and you walk two miles, as fast as you can walk that two miles, and tomorrow, you repeated it, but threw ten pounds into a backpack while you did it, and repeated that every day for a month; you would be fitter—faster and stronger—than you are today.
