You can “hack” a lot of your health, diet, and lifestyle. You can cook the entire week’s meals ahead of time, buy high-quality prepackaged foods and ready-to-cook meals, cover your nutritional bases with smart supplementation. You can condense your training time by choosing the right exercises and upping the intensity to a sufficient level. You can fast-track your stamina in a fraction of the time with sprints and intervals. (This Mark's Daily Apple article was written by Mark Sisson, and is narrated by Tina Leaman)
