Roger Federer
20 Grand Slam titles
The most graceful mover tennis has produced — a metronome of efficiency across two decades.
From nine measurements alone — no name, no photo — the AI ranked tennis first for this build.
⚡ The AI even named Roger Federer as an example athlete for this build — without ever seeing the name.

WHAT THE AI SAW
Build type
ATHLETIC BUILD
- •Positive ape index (+4 cm) providing natural reach advantage
- •Long legs relative to torso (inseam ~46.5% of height) for stride, lunge, and block mechanics
- •Pronounced shoulder-to-hip ratio (~1.26) indicating strong rotational power potential
- •Large hands and feet enhancing grip, paddle/propulsion, and stability
THE AI'S SPORT RANKINGS
Tennis (singles)
Ideal blend of height for serve leverage, slightly positive wingspan for reach, long legs for court coverage, and strong shoulder-to-hip ratio for rotational power. Large hands aid grip strength and spin control.
Javelin throw
Long legs facilitate a fast approach and powerful block; broad shoulders and large hands aid force transfer and clean release; positive reach and height are within successful elite ranges.
Mixed Martial Arts (Middleweight)
Height and reach align well with middleweight norms, offering striking range; long legs benefit kicking and guard work; broad shoulders and 85 kg frame support power and clinch control; large hands help glove control and grappling.
Fencing (Épée)
Positive ape index and long legs increase effective distance and lunge reach; height confers a natural distance-management edge. Not extreme reach, but biomechanically favorable for épée tactics.
Swimming (50–100 m freestyle)
Above-average wingspan and large feet/hands aid propulsion; height is adequate for sprint events. Slightly longer legs vs. torso is less typical than the long-torso elite archetype, so advantages are solid but not maximized.
BIOMECHANICAL READ
- 1Efficient levers for rotation-driven power: broad shoulders and narrow hips favor high racket/arm speed and throwing velocity.
- 2Reach and limb length support striking range, defensive framing, and interception (tennis returns, MMA striking, fencing).
- 3Long legs with solid mass enable powerful acceleration, long court coverage/lunge distance, and effective block step in javelin.
- 4Hand size improves grip security (racquet, gi, glove) and fine control at release (javelin) or contact (tennis).
- 5Height/mass balance (185 cm/85 kg) supports explosive strength while remaining agile across multidirectional sports.
LESS ADVANTAGEOUS IN
- •Elite heavyweight rowing (height disadvantage vs. taller rowers)
- •Professional basketball/men’s volleyball (height ceilings higher at elite level)
- •Olympic weightlifting and powerlifting (longer limbs reduce leverage/ROM efficiency)
- •Marathon/ultra-distance running (body mass not optimized for economy)
- •Artistic gymnastics (greater stature and limb length hinder rotations)
- •Rock climbing/bouldering at elite levels (extra mass; only modest ape index)
METHODOLOGY
The AI analysis above was generated from the nine measurements listed — nothing else. The model never saw Roger Federer's name, photo, or sport; it received the same anonymous input as any visitor who uses the tool. The verdict compares its blind rankings with reality.
Measurements marked Est. are not publicly documented and were estimated from published data using the noted anthropometric ratios.
