He says many high-performing people train 4 to 5 times per week and eat clean but see no visible results, so the approach starts with advanced blood work, a comprehensive questionnaire, and a Dexa body scan to stop guessing. Next comes repairing foundations like sleep, recovery, stress, habits, and nutrition before rebuilding with efficient training for muscle, fat loss, and strength based on abilities and available time. He shares his own results from combining data, structure, and nutrition, leading to his best shape at age 44 and a stated biological age of 31.
