My old college roommate used to grind 3 hours daily at the gym chasing quick gains. By 35, his knees and shoulders ached so bad he could barely carry groceries without wincing. Today I read about the Decade Test, before picking a routine, ask if it’ll benefit you in 10 years. Research says beyond 120 minutes of strength training weekly, benefits stop. He could’ve saved himself so much pain thinking long-term. I’ve started 20-minute post-school walks; nothing fancy, just moving. I want to be sipping lattes and grading essays pain-free at 51.
