Last week I promised you 3 numbers that matter more than your weight.
I was going to talk about blood markers. But honestly? There are 3 numbers that predict your health even better than anything on a blood report.
And you can test all 3 at home, right now, in 5 minutes.
Here’s the first test:
Can you climb 4 flights of stairs in under 60 seconds without stopping?
If you just thought “probably” but aren’t sure, keep reading.
A study from the European Society of Cardiology tracked thousands of adults and timed how long they took to climb 4 flights of stairs.
The results were striking:
- 30% 10-year mortality rate for people who took over 90 seconds
- <10% 10-year mortality for those who did it under 45 seconds
Not your cholesterol. Not your BMI. Not your fasting sugar. How fast you climb stairs.
“I was 22 kg overweight and flying between 3 continents.”
Nitish is a 33-year-old software engineer at one of India’s biggest IT firms. India one week, South Africa the next, Europe after that.
He had tried everything. Every time he started a routine, a flight would knock it out.
NUMBER 1: VO2 Max: Your Cardio Engine
The Cleveland Clinic studied 122,007 adults over two decades. People with the lowest cardio fitness had 4x higher mortality than those with the highest.
For comparison: smoking increases mortality risk by 1.4x. Low cardio fitness is literally more dangerous than smoking.
NUMBER 2: Grip Strength: Your Full-Body Strength Signal
The Lancet PURE study followed 139,691 people across 17 countries. Grip strength predicted death better than blood pressure.
NUMBER 3: Leg Strength & Muscle Mass: Your Longevity Foundation
After age 30, you lose 3-5% of your muscle mass every decade. By 50, most professionals have lost 15-20% of their muscle and don’t even know it.
- 51-65% higher mortality risk with low quadriceps strength
- 3x mortality risk if chair-stand takes over 15 seconds
What changed when we focused on the right numbers
We didn’t put Nitish on a crash diet. We built a system that worked in India, in South Africa, and in Europe.
Nitish’s Results
- Weight: Down 22 kg. Kept it off across 3 continents.
- VO2 Max: Up 20%. His stair test? Crushed it.
- Grip Strength: Up 30%. Stronger than he’s ever been.
- Stamina: Runs regularly. Trains consistently. More energy than his 20s.
Test Your 3 Numbers (5 Minutes)
Test 1: The Stair Test (VO2 Max)
Find a building with 4 floors. Walk up at a brisk pace. Time yourself.
- Under 45 sec: Excellent
- 45-60 sec: Good
- 60-90 sec: Needs improvement
- Over 90 sec: Time to act
Test 2: The Hang Test (Grip Strength)
Find a bar or sturdy overhead surface. Hang with both hands. Time it.
- Over 60 sec: Strong
- 30-60 sec: Average
- Under 30 sec: Needs serious work
Test 3: The Chair Stand (Leg Strength)
Sit in a regular chair. Stand up and sit back down as many times as you can in 30 seconds. No hands.
- 14+ reps: Good
- 10-13 reps: Below average
- Under 10 reps: Your legs need attention
If your stair test was over 90 seconds, don’t panic. That number is incredibly responsive to training. I’ve seen clients cut their time in half within 8 weeks.
