8 tests that predict how long you'll live (90% of people fail #8):
Test 1: Metabolic Health Markers

Waist to height ratio: under .5
Fasting glucose: under 100 mg/dL
HbA1c: at or below 5.6
FFMI: above 18 (men) / 15 (women)

This is the foundation. Every other test builds on it.
Test 2: Sit-to-Stand Power Test

From a chair, stand up and sit back down 5 times. No hands. Under 12 seconds.

Power declines faster with age than strength does. Most people in their 40s assume they'll pass this easily.

Try it with a timer before you decide.
Test 3: Loaded Ruck Walk

Walk 1 mile with 20-25% of your bodyweight on your back. Under 20 minutes. Breathing through your nose the entire time.

If you have to open your mouth to keep the pace, your aerobic base isn't where it needs to be. Image
Test 4: Push-Up Test

20 consecutive push-ups for men. 10 for women.

A Harvard study found men who completed 40+ push-ups had dramatically lower cardiovascular risk than those who could barely manage 10.

This may sound easy but you'd be surprised at how many fail this.
Test 5: Grip Strength

Dead hang from a bar for 60 seconds.

Grip strength is one of the most consistent predictors of all-cause mortality in the research.

When your grip goes, your independence tends to follow.
Test 6: Cardiovascular Capacity

Target: VO2max above 40 ml/kg/min or 9:30 minutes mile or 10 minute 3 mile cycle. RHR below 60 bpm.

A simple test: walk up 3 flights of stairs and hold a conversation at the top.

If you're winded, your cardiovascular system is aging faster than you are.
Test 7: Balance

Stand on one leg, eyes closed, for 30 seconds.

A 2023 study found that adults who couldn't hold a 10-second single-leg stand had nearly double the mortality risk over the following 7 years.

Try it right now.
Test 8: Mobility (The One Most People Fail)

Lower yourself to the floor cross-legged without using your hands or knees. Then stand back up the same way.

Each assist costs you a point from 10.

Score below 4? Research shows you're 5-6x more likely to die during the study period than high scorers.
Anyone above 35 should be able to pass these with ease but the true test is being able to pass them when you're 65 and older.

If you can't pass these then get to work ASAP. Your quality of life is at stake.

The Top 4 Most Underrated Supplements

1) CoQ10
2) Glycine
3) L-theanine
4) Psyllium husk

Here's why 👇🏼
1) Coenzyme Q10 (CoQ10)

Your mitochondria need this to produce energy.

Without it, your cells run on fumes.

Here's the issue: CoQ10 levels drop as you age. And if you're on a statin, they drop even faster.

Supplementing can improve energy, heart health, and exercise recovery.
How to take CoQ10:

Take 100-200mg daily with a meal containing fat. Fat increases absorption significantly.

Use the ubiquinol form if you're over 40. It's more bioavailable than ubiquinone.

Most people notice improved energy within 2-4 weeks.

If I woke up 20 pounds overweight and needed to lose it all by summer, this is EXACTLY what I'd do:

1. Stop eating at least 3-5 hours before bed. Set a hard stop. This prevents horrible food decisions and improves the quality of your sleep, which regulates hunger the next day.
2. Multiply your bodyweight by 12. That will be your daily calorie intake.

3. Multiply your bodyweight by .7, and that will be the daily grams of protein you need to eat to maintain/build muscle while burning fat.

4. To keep it easy, focus on hitting your calories and protein.
5. Fill your daily nutrition with these foods:

Greek yogurt
Water, coffee, and tea
Lean ground beef (extra-lean if you can)
Chicken breast and thighs
Turkey (ground or breast)
Fatty fish
Eggs and egg whites
Cottage cheese
Leafy greens
Potatoes​
Shellfish
Beans and lentils
Berries
Apples, oranges, kiwi, and grapefruit for higher-fiber fruit
Green cruciferous vegetables
Other high‑volume veg (cauliflower, zucchini, mushrooms, peppers, asparagus, cucumbers)

8 health trends that need to die in 2026:

1) Cold plunging.

Good for dopamine but studies show it blunts muscle growth and it doesn't improve recovery in a meaningful way.

For most people it's become a virtue signaling marathon on Instagram rather than an actual health tool.
2) Extreme "clean eating."

The moment you label food "clean" or "dirty" you've started a war with your plate.

I've watched this push people into disordered eating and social isolation.

You can be lean and healthy eating whole foods diet with room for your favorite foods.
3) Obsessive biohacking gadgets.

CGMs when you're not diabetic. 4 wearables on your wrist. Biofeedback devices on your nightstand.

You're turning normal body variation into anxiety.

Steps. Sleep. Weights. Nature. That covers 90% of the game. Stop overcomplicating it.

1 in 3 Americans are insulin resistant and it's silently killing them from the inside.

What most don't realize is you can reverse it in 3 to 6 months without a single medication.

Here's the exact protocol on how to do it (bookmark this): Image
8 Warning Signs of Insulin Resistance

1. Excess belly fat
2. Brain fog
3. Constant hunger
4. Low energy
5. High inflammation
6. High blood pressure
7. High blood sugar
8. High Triglycerides
It's a sign of high glucose and high insulin.

Your cells ignore insulin's signal to absorb glucose thus your body pumps out more insulin to compensate.

The result is fat storage, chronic fatigue, brain fog, and type 2 diabetes.

The good news is this is fixable with the right systems.

If you want to live to 100 or longer track these 6 key metrics:

1. Cardiorespiratory fitness

What to track: VO₂max, one mile run times or 3 mile cycle times.

Your cardio system is one of the best predictors all-cause mortality.
2. Muscle strength and lean mass

What to track: grip strength, FFMI, basic strength standards.

Low strength and muscle mass are hallmarks of frailty and higher death risk as we age.

High strength and muscle mass equal a better quality of life.
3. Autonomic nervous system health

What to track: heart rate variability (HRV) and resting heart rate trends.

These reflect stress resilience and recovery capacity, not just “fitness.”

If you need to get your shit together in 2026, read this:
1. Stop being easily offended. If you’re easily offended you’re easily manipulated.

2. Get your body lean and healthy. Getting in shape is the lead domino that makes your entire life better.
3. Treat food as fuel for the brain and body. Put garbage in and you get garbage back. Put high quality foods in and you’ll improve your energy and mental health.

4. Sleep is your waste removal system. Prioritize it like your life depended on it.
