What regimens help a busy 58-year-old balance strength, cardio, nutrition, mobility,

[MatthewRR]

I'm a 58-year-old freelance consultant, and my recent annual physical showed slightly elevated blood pressure and a decline in muscle mass, which has me seriously focusing on a long-term plan for healthy aging. I want to move beyond generic advice and build a sustainable routine that balances strength training, cardiovascular health, and cognitive engagement. I'm particularly interested in evidence-based approaches to nutrition for maintaining metabolic health and strategies for preserving mobility and balance to prevent falls. For others navigating this mid-life pivot, what specific regimens, resources, or lifestyle adjustments have you found most effective? How do you balance the need for structured exercise with the reality of a busy, sometimes sedentary work life?
