JJ Virgin explains that muscle loss accelerates after 40, hitting 1% yearly and doubling by 60. She recommends compound resistance training twice weekly per muscle group, adequate protein spread across meals, Zone 2 cardio, and 7-9 hours of sleep. Track progress with DEXA scans or home bioimpedance scales, not just the scale.
