Fitness is the physical foundation. Everything — energy, mood, confidence, sleep, cognitive performance, longevity — improves when you’re physically fit. It’s the highest-ROI habit you can have.
The basics that work:
- Strength training — 3-4 times a week. Compound movements: squats, deadlifts, bench press, overhead press, rows, pull-ups. These build functional strength and preserve muscle mass as you age.
- Cardio — both kinds. Zone 2 (easy, conversational pace) for heart health and endurance — 150+ minutes per week. High intensity (sprints, intervals) for metabolic health — 1-2 sessions per week.
- Mobility — stretching, yoga, movement practice. Flexibility and joint health become increasingly important with age. The strongest person who can’t touch their toes is leaving performance on the table.
- Recovery — sleep is where you actually get stronger. 7-9 hours. Training breaks you down; rest builds you up.
The psychological benefits are at least as important as the physical ones:
- Exercise is the most effective natural antidepressant
- Regular training builds discipline that transfers to every other area of life
- Physical confidence changes how you carry yourself and how others respond to you
- The practice of showing up when you don’t feel like it is a life skill
The biggest obstacle isn’t knowledge — it’s consistency. Don’t optimize. Just show up. A mediocre workout you do consistently beats a perfect program you abandon after three weeks.
Start where you are. Not where you think you should be. Progress is the goal, not perfection.
