The Global Standard of Strength: Why SBD Matters

In the modern fitness landscape, strength is no longer subjective. It is a metric, quantifiable and comparable across borders. HobbyTier standardizes these metrics to provide a unified language for lifters worldwide.
1. The Evolution of Strength Assessment
Historically, strength was visually assessed—the size of the biceps or the breadth of the shoulders. However, hypertrophy does not always linearly correlate with neuromuscular force production. With the advent of Powerlifting in the mid-20th century, a new standard emerged: SBD (Squat, Bench Press, Deadlift).
These three movements were not chosen at random. They represent the maximal capacity of the human kinetic chain:
- Squat (Knee Dominant / Pushing): The "King of Exercises". It tests the entire posterior chain, core rigidity, and quad strength. It is the definitive test of lower-body power.
- Bench Press (Horizontal Pushing): The primary upper-body strength metric, engaging the pectoralis major, anterior deltoids, and triceps brachii.
- Deadlift (Hip Dominant / Pulling): The ultimate test of central nervous system (CNS) recruitment and grip strength. It is the purest form of moving an object from point A to point B.
2. The Problem with Regional Standards
Every gym culture has its benchmarks. In the US, the "1000lb Club" (453.6kg) is the entry-level badge of honor. In South Korea, the "3대 500" (500kg Total) became a cultural phenomenon, popularized by fitness YouTubers and the "Under Armour Squad" meme.
However, absolute numbers are inherently unfair. Is a 500kg total impressive?
- For a 60kg lifter? Absolutely elite. That is 8.3x bodyweight.
- For a 120kg lifter? Respectable, but intermediate. That is 4.1x bodyweight.
This discrepancy led to the development of Relative Strength Coefficients.
3. The Science of Normalization: Wilks to DOTS
The Universal Language of Iron

A 100kg deadlift is 100kg in Seoul, 100kg in New York, and 100kg in London. Gravity is constant (mostly). Standardization allows us to gamify fitness. It turns a solitary pursuit into a global leaderboard.
The Wilks Formula
Developed by Robert Wilks in Australia, this formula was the gold standard for decades. It used a polynomial equation to compare lifters of different body weights across genders. However, statistical analysis revealed a bias: it favored middleweight lifters while disadvantaging super-heavyweights and very light lifters.
The DOTS Coefficient
The Dynamic Objective Team Scoring (DOTS) is the modern replacement adopted by the IPF (International Powerlifting Federation). It provides a flatter curve, ensuring that a 50kg lifter and a 150kg lifter can be compared with higher statistical accuracy. HobbyTier utilizes the **DOTS mechanism** in our backend to calculate your "Tier Score".
4. The HobbyTier Methodology
We believe that gamification drives progress. A raw number is just data; a "Tier" is an identity. Our system aggregates data from OpenPowerlifting.org (millions of verified competition results) to create a bell curve distribution.
- Bronze: Top 80% (Beginner) - Mastering the movements.
- Silver: Top 50% (Intermediate) - Linear progression ends; programming begins.
- Gold: Top 20% (Advanced) - Years of dedicated training.
- Platinum: Top 5% (Elite) - Regional competitor level.
- Diamond: Top 1% (National Elite) - National qualifier level.
- Grandmaster: Top 0.1% (World Class) - IPF Worlds caliber.
5. Why Measurement Matters
"You cannot improve what you do not measure." Without a standardized baseline, training becomes distinct from exercising.Exercise is physical activity for health. Training is physical activity with a measurable goal.
By inputting your numbers into HobbyTier, you are not just checking a rank. You are placing yourself on the global map of human strength potential. It is a reality check, a roadmap, and a motivation tool all in one.
Conclusion: Strength is the foundation of all athletic endeavors. Whether you are a cyclist, a runner, or a gamer, having a strong posterior chain and core improves performance and longevity. Start measuring today.
