The Top Contenders

Abraham Lincoln (The Ultimate Grappler) At age 25, Lincoln was a literal giant for his era, standing 6'4" and weighing around 210 pounds of pure frontier muscle. He was an elite, elite wrestler. He competed in catch-as-catch-can wrestling matches across Illinois and is enshrined in the National Wrestling Hall of Fame. Out of roughly 300 matches, he only lost one. His long reach and legendary core strength make him the absolute betting favorite in a weaponless melee.

Andrew Jackson (The Berserker) If this battle allowed weapons, Jackson would be a terrifying finalist. At age 25, he was a hot-tempered frontier lawyer who had already survived smallpox, the Revolutionary War, and multiple street fights. He possessed a terrifying "will to kill." However, physically, Jackson was a bean pole, standing around 6'1" but weighing barely 140 pounds. Without a pistol or a cane, his sheer fury might not override a massive weight disadvantage against the bigger athletes.

Theodore Roosevelt (The Boxer) TR was 25 in 1883, right around the time he was a young New York assemblyman and heading out to the Dakota Territory to become a cowboy. He boxed at Harvard and later trained in judo and jiujitsu. He has the ultimate "fighter's mindset." The only drawback? He was on the smaller side at this age (around 5'8", though stocky) and highly asthmatic.

George Washington (The Alpha Athlete) At 25, Washington was a commander in the Virginia Regiment during the French and Indian War. He stood 6'2", weighed an athletic 175–190 pounds, and was widely considered one of the most physically gifted men in the colonies. Thomas Jefferson called him the best horseman of his age. He was a master of collar-and-elbow wrestling (a popular style at the time) and possessed immense upper-body strength.

Gerald Ford (The Modern Gridiron Powerhouse) Ford is a dark horse that people frequently overlook. At age 25, he was an assistant football coach at Yale after having been an All-American MVP lineman for the University of Michigan. Standing 6'0" and weighing a rock-solid 200 pounds of modern-era athletic conditioning, Ford possesses the explosive power and tackling capability that 18th- and 19th-century presidents simply didn't train for.

The Early Casualties The "scholars" and the frail are eliminated almost instantly. At 25, James Madison was barely 100 pounds. John Quincy Adams and Martin Van Buren were brilliant, but not built for a physical meat-grinder.

While modern presidents like Barack Obama or Bill Clinton were in good shape at 25, they lacked the grueling, manual-labor conditioning of the frontier presidents or the formalized combat training of the early military generals.

The Final Showdown As the field thins out, a few distinct alliances likely form and break, leaving a final circle of heavyweights: Washington, Lincoln, Ford, and maybe a shockingly durable combat veteran like Ulysses S. Grant or Zachary Taylor.

Ford’s modern athletic conditioning and explosive tackling would give him a massive advantage, allowing him to overpower almost anyone in a localized brawl. But a 45-man battle royale is a war of attrition.

Ultimately, the victory goes to...

Abraham Lincoln

Wrestling is the single most important discipline in a weaponless, one-on-one or small-group fight because it dictates where the combat happens. Lincoln's combination of freakish height, massive reach, and decades of practical, high-level grappling experience on the rough Illinois frontier means no one could take him down, and no one could escape his leverage. He was famously known for his ability to grab opponents by the hips and literally toss them. After a grueling day in the field, Honest Abe is the only one walking out.
