FFMI by Sport: Professional Athletes Across Different Disciplines

FFMI Across Sports: What Elite Athletes Actually Measure

Different sports require different levels of muscularity. A marathon runner optimizes for endurance (low FFMI), while a powerlifter maximizes strength (high FFMI). This analysis examines FFMI across major sports, revealing realistic targets for natural athletes.

Strength Sports (Highest FFMI)

Powerlifting (Drug-Tested Federations)

Average FFMI: 24-27
Elite Natural Range: 25-26
Why: Maximum muscle mass directly correlates with strength potential

Notable Examples:

• IPF World Champions: FFMI 25-27
• National-level drug-tested lifters: FFMI 24-26

Olympic Weightlifting

Average FFMI: 24-26
Elite Range: 25-27
Why: Power-to-weight ratio matters, but muscle mass crucial for absolute strength

Note: Olympic weightlifting has inconsistent drug testing; many top athletes likely enhanced.

Strongman

Average FFMI: 26-30+
Elite Natural Range: 25-27
Why: No weight classes in most competitions, absolute mass advantageous

Reality: Professional strongman is largely enhanced. Natural strongman competitors typically FFMI 25-27.

Physique Sports

Natural Bodybuilding

Men: FFMI 23-25
Women: FFMI 19-21
Why: Maximum muscle mass at low body fat is the goal

Drug-Tested Organizations:

• PNBA/INBA: Polygraph + urine testing
• IFPA: Long-term testing protocols
• Average winners: Men FFMI 23-25, Women FFMI 19-21

Men's Physique (Enhanced Divisions)

Average FFMI: 27-30
Why: No drug testing, PED use prevalent
Note: Do NOT use as natural comparison

Team Sports

American Football

By Position:

• Offensive/Defensive Linemen: FFMI 27-32 (mostly enhanced at NFL level)
• Linebackers: FFMI 25-28
• Running Backs: FFMI 24-26
• Wide Receivers: FFMI 22-24
• Defensive Backs: FFMI 22-24
• Quarterbacks: FFMI 22-24

College (Drug-Tested):

• Division I linemen average: FFMI 25-27
• Skill positions: FFMI 22-25

Rugby

By Position:

• Forwards (Props, Locks): FFMI 26-28
• Back Row: FFMI 24-26
• Backs: FFMI 22-24

Note: Professional rugby has limited drug testing. These numbers likely include some enhanced athletes.

Basketball

NBA Average: FFMI 22-24
Why: Balance of size, speed, and endurance

By Position:

• Centers/Power Forwards: FFMI 23-25
• Small Forwards: FFMI 22-24
• Guards: FFMI 21-23

Soccer/Football

Average: FFMI 20-23
Why: Endurance prioritized over maximum muscle mass

By Position:

• Goalkeepers: FFMI 22-24
• Center Backs: FFMI 22-23
• Midfielders: FFMI 20-22
• Forwards: FFMI 20-22

Combat Sports

Mixed Martial Arts (MMA)

Average: FFMI 22-25
Why: Weight classes require optimization of strength-to-weight

By Weight Class:

• Lightweight-Welterweight: FFMI 23-25
• Middleweight-Light Heavyweight: FFMI 24-26
• Heavyweight: FFMI 23-27

Note: UFC has USADA testing (strict). Most UFC fighters are likely natural, making these realistic natural FFMI targets.

Boxing

Average: FFMI 21-24
Why: Endurance crucial, excessive muscle mass disadvantageous

By Weight:

• Lightweight-Welterweight: FFMI 22-24
• Middleweight-Light Heavyweight: FFMI 23-25
• Heavyweight: FFMI 23-26

Wrestling

College/Olympic: FFMI 23-26
Why: Strength-to-weight ratio critical

High School: FFMI 20-23

Track & Field

Sprinters (100m-400m)

Average: FFMI 22-24
Why: Power and explosiveness require significant muscle mass

Elite Examples:

• Usain Bolt: Estimated FFMI ~23
• Justin Gatlin: Estimated FFMI ~24

Middle Distance (800m-1500m)

Average: FFMI 20-22
Why: Balance of power and endurance

Distance Runners (5K+, Marathon)

Average: FFMI 17-19
Why: Lower body weight improves efficiency for endurance

Elite Marathoners: FFMI 17-18 (Eliud Kipchoge ~FFMI 17)

Throwers (Shot Put, Discus, Hammer)

Average: FFMI 26-30
Why: Absolute power and mass crucial

Note: High prevalence of PED use at elite level.

Jumpers (High Jump, Long Jump, Triple Jump)

Average: FFMI 21-23
Why: Power-to-weight ratio optimized

CrossFit & Functional Fitness

CrossFit Games Athletes

Men: FFMI 24-26
Women: FFMI 19-21

Why: Requires balance of strength, power, and endurance

Note: CrossFit has some drug testing at Games level, but inconsistent. Many top athletes likely natural.

Endurance Sports (Lowest FFMI)

Cycling (Road)

Average: FFMI 18-20
Why: Low body weight crucial for climbing efficiency

Swimming

Average: FFMI 21-23
Why: Upper body strength important but excessive muscle creates drag

Triathlon

Average: FFMI 19-21
Why: Endurance prioritized across three disciplines

Key Insights for Natural Athletes

Sports Requiring High FFMI (24-26):

• Powerlifting
• Olympic weightlifting
• Natural bodybuilding
• Wrestling (heavier weights)
• Football (linemen)
• Rugby (forwards)

Sports with Moderate FFMI (21-24):

• MMA
• Boxing
• Basketball
• Football (skill positions)
• Soccer/Football
• Sprinting
• CrossFit

Sports with Lower FFMI (17-21):

• Distance running
• Cycling
• Triathlon

The Bottom Line

Realistic Natural FFMI by Sport:

1. If pursuing strength sports: Target FFMI 24-26
2. If pursuing combat sports: Target FFMI 23-25
3. If pursuing team sports: Target FFMI 22-24 (position-dependent)
4. If pursuing endurance sports: FFMI 18-21 optimal

Don't blindly chase FFMI 25+ if your sport doesn't require it. A basketball player at FFMI 27 would be too slow; a marathoner at FFMI 24 would be too heavy. Optimize your FFMI for your specific athletic goals.

Remember: Many professional athletes in non-tested sports are enhanced. Use drug-tested competition results as realistic natural targets.
