Health and Body

Physical health, fitness, and understanding your body at 40+.

The Reality at 40

Your body at 40 is different from your body at 25. Not worse, just different. Understanding these changes lets you work with your biology, not against it.

What Changes

The Good News

• Muscle responds to training at any age
• Cardiovascular fitness is highly trainable
• Most decline is from disuse, not aging
• Lifestyle changes have massive impact
• You can be fitter at 45 than you were at 35

The Non-Negotiable Health Practices

1. Annual Physical with Full Bloodwork

Not just "Doc says I'm fine." Get numbers you can track:

Essential markers:

Track these over time. A single snapshot is less valuable than trends.

2. Know Your Critical Numbers

Beyond bloodwork, know:

3. Cardiovascular Exercise

Heart disease is the #1 killer of men. Cardiovascular fitness is protective.

Minimum: 150 minutes moderate or 75 minutes vigorous per week

Types:

• Zone 2 training (can hold conversation): 80% of cardio time
• Higher intensity intervals: 20% of cardio time

Good options at 40+:

• Walking (underrated, joint-friendly)
• Cycling (low impact)
• Swimming (zero impact)
• Rowing (full body)
• Hiking (mental health bonus)

Key insight: Consistency beats intensity. 30 minutes daily beats one 3-hour session weekly.

4. Strength Training

This is non-negotiable. Muscle loss (sarcopenia) is one of the biggest threats to quality of life as you age.

Minimum: 2-3 sessions per week

Focus on:

• Compound movements (squat, deadlift, press, row, pull)
• Progressive overload (gradually increase difficulty)
• Full range of motion
• Recovery (you need more than you did at 25)

Program considerations at 40+:

• Warm up longer (10-15 minutes)
• Prioritize mobility alongside strength
• Don't ego lift. Injury recovery is slow
• Higher reps, moderate weight often beats heavy singles
• Listen to your body (pain vs. discomfort)

Sample weekly structure:

Monday: Push (chest, shoulders, triceps)
Wednesday: Pull (back, biceps)
Friday: Legs + Core
Optional: Saturday light cardio/mobility

5. Sleep

Sleep is when you recover, build muscle, consolidate memory, and regulate hormones. It's not optional.

Target: 7-9 hours per night

Sleep quality matters more than duration:

• Deep sleep: Physical recovery
• REM sleep: Mental recovery, memory

Sleep hygiene for 40+:

• Consistent sleep/wake times (even weekends)
• Dark, cool room (65-68°F)
• No screens 1 hour before bed
• Limit alcohol (disrupts sleep architecture)
• Limit caffeine after noon
• Consider magnesium supplementation
• Address sleep apnea if suspected (common in men 40+)

Warning signs of sleep problems:

• Snoring
• Waking unrefreshed
• Daytime fatigue
• Difficulty concentrating
• Irritability

Get a sleep study if these apply. Sleep apnea is seriously underdiagnosed and dangerous.

Nutrition at 40+

The Basics Still Apply

• Eat mostly whole foods
• Plenty of vegetables
• Adequate protein
• Limit processed foods
• Limit sugar
• Moderate alcohol

Protein Becomes More Important

Muscle protein synthesis becomes less efficient with age. You need more protein to get the same effect.

Target: 0.7-1g per pound of body weight

• 180 lb man = 130-180g protein daily

Distribute throughout the day:

• 30-40g per meal
• Protein at every meal
• Post-workout protein within 2 hours

Good sources:

• Meat, fish, poultry
• Eggs
• Greek yogurt
• Cottage cheese
• Whey protein (convenient supplement)

Calorie Considerations

Metabolism slows. Activity often decreases. Weight gain becomes easier.

Options:

1. Increase activity to maintain intake
2. Reduce intake to match lower expenditure
3. Build muscle (increases metabolic rate)

Practical approach:

• Track what you eat for a week (awareness)
• Adjust based on whether you're gaining/losing
• Don't diet aggressively (muscle loss, rebound)

What to Limit

Consider Supplementation

Evidence-backed supplements:

Get blood tests before other supplements. Don't take what you don't need.

Hormones

Testosterone

Testosterone naturally declines ~1% per year after 30. Symptoms of low T:

• Fatigue
• Reduced libido
• Difficulty building muscle
• Increased body fat
• Depression/irritability
• Brain fog

Before considering TRT (testosterone replacement):

1. Optimize lifestyle first:

   • Sleep 7+ hours
   • Lift weights
   • Maintain healthy body fat
   • Manage stress
   • Limit alcohol
   • Eat adequate protein and healthy fats

2. Get tested properly:

   • Total and free testosterone
   • SHBG
   • LH and FSH
   • Estradiol
   • Test in morning (levels are highest)

3. If levels are truly low (under 300 ng/dL with symptoms):

   • Discuss TRT with a knowledgeable doctor
   • Understand the commitment (often lifelong)
   • Monitor estrogen, hematocrit, PSA
   • Consider fertility implications

TRT is not a shortcut. It's a medical treatment for a medical condition.

Common Health Issues at 40+

Heart Disease

The #1 killer. Risk factors:

• High blood pressure
• High LDL cholesterol
• Smoking
• Diabetes
• Obesity
• Sedentary lifestyle
• Stress
• Family history

Prevention:

• Know your numbers
• Exercise regularly
• Maintain healthy weight
• Don't smoke
• Manage stress
• Consider statins if indicated

Type 2 Diabetes

Increasingly common. Often preventable.

Risk factors:

• Overweight
• Sedentary
• Family history
• High blood sugar

Prevention:

• Maintain healthy weight
• Exercise regularly
• Limit sugar and refined carbs
• Get tested regularly

Cancer Screenings

Other Common Issues

• Erectile dysfunction: Often first sign of cardiovascular issues. Get checked.
• Prostate enlargement (BPH): Common, manageable. See urologist if symptoms.
• Joint issues: Mobility work, smart training, adequate recovery.
• Sleep apnea: Very common, underdiagnosed. Get sleep study if suspected.

The Practical Health System

Daily

• 7+ hours sleep
• Move your body
• Eat mostly whole foods
• Adequate protein
• Limited alcohol

Weekly

• 3+ strength training sessions
• 3+ cardio sessions
• One full rest day

Monthly

• Review progress
• Adjust training if needed
• Check body composition trends

Annually

• Full physical with bloodwork
• Dental checkup
• Eye exam
• Skin check
• Any age-appropriate screenings

The Mindset

You're not trying to look 25. You're trying to be a high-functioning, healthy, capable man who can do what he wants physically for decades to come.

The goal:

• Play with grandchildren
• Hike at 70
• Maintain independence
• Die quickly at an old age, not slowly from preventable disease

That requires action now, not later.
