MrBeast Lost 50 Pounds and His Grip Strength Shocked Everyone (Even After Zero Training)

Mr. Beast, the biggest YouTuber on the planet, just put his strength to the test.

And the results might surprise you.

After losing 50 pounds and transforming his physique from 40% body fat, Jimmy Donaldson faced off against fitness expert Jesse James West in five intense physical challenges.

The stakes? Control of Mr. Beast’s Instagram account versus gaining him as a 10 million subscriber.

From Fat to Fit: Mr. Beast’s Remarkable Transformation

Jimmy’s weight loss journey has been nothing short of impressive. Starting at over 50 pounds heavier with 40% body fat, he shed the weight through dedication and consistency.

Yeah. Play the clip. I was fat. Very fat. 40% body fat.

Now weighing around 160-170 pounds, Mr. Beast stands at a similar body weight to West, setting up an interesting showdown between experience and natural athleticism.

Challenge One: Grip Strength Showdown

First up was grip strength testing, something Jimmy admitted he’d never measured before.

Oh gosh, I’ve never measured my grip strength.

Despite his inexperience, Mr. Beast squeezed out an impressive 143 on the grip strength meter. West, who has been training for 10 years, managed only 151—barely beating Jimmy by 8 points.

The close margin shocked both competitors and demonstrated that Jimmy’s transformation wasn’t just about losing weight. He’d built legitimate strength along the way.

Challenge Two: Memory Meets Muscle

Filmed on the actual set of Beast Games 2 with $5 million as a backdrop, the second challenge combined mental acuity with physical endurance.

Competitors had 10 seconds to memorize five objects in order, complete 50 push-ups, then arrange the objects correctly. But this time, Jimmy had backup—his friend Mack, who lost over 100 pounds in 6 months after appearing in a Mr. Beast transformation video.

The team strategy proved decisive. While Mack focused solely on push-ups and Jimmy memorized the sequence, West had to split his attention between both tasks.

We both memorized. You do push-up first. The second you get tired, I’ll jump in.

Team Mr. Beast completed the challenge first, evening the score at 1-1.

Challenge Three: Pull-Up Dominance

Pull-ups exposed the gap between casual fitness and dedicated training. West, despite claiming he doesn’t regularly practice pull-ups, demonstrated his decade of experience with 27 total reps.

Jimmy and Mack combined managed only 15 pull-ups together. Though Jimmy’s form looked clean and he pushed through fatigue admirably, the numbers didn’t lie.

West took the lead 2-1, putting Mr. Beast’s Instagram in serious jeopardy.

Challenge Four: Tire Flipping Chaos

Flipping a massive tire from one end of the Beast Games set to the other tested raw power and endurance. Each roll of the tire added a one-second penalty.

West went first, battling through exhaustion from the previous pull-up challenge. Despite mind games from Jimmy and a one-second penalty, he posted a time of 24 seconds.

I think that person over there needs your help. Oh my god, that’s a burning building.

After debate about strategy, Jimmy and Mack worked together. Their aggressive approach nearly backfired with multiple close calls on rolling the tire, but they finished in 22 seconds.

The score tied at 2-2, everything came down to one final challenge.

Challenge Five: Basketball Free Throws Decide Everything

Mr. Beast chose basketball for the decisive challenge, claiming expertise in the sport. The rules were simple: first person to make five free throws wins.

What followed was a comedy of errors mixed with clutch shooting. West struggled dramatically with his form, missing shot after shot while Jimmy calmly sank basket after basket.

Wait, if you’re shooting that way, why are you pointing your feet this way?

Despite coaching from Jimmy on proper technique, West couldn’t find his rhythm. Meanwhile, Mr. Beast demonstrated why he chose this challenge, showing consistent shooting form developed from years of recreational play.

Jimmy secured the final point and won the overall battle 3-2, earning West as his 10 millionth subscriber while saving his Instagram from a photoshopped steroid post.

What This Competition Reveals About Fitness

The challenges demonstrated several important fitness principles:

• Weight loss builds functional strength: Jimmy’s grip strength nearly matched a 10-year training veteran
• Specificity matters: West dominated pull-ups due to training experience, while Jimmy excelled at basketball through practice
• Teamwork amplifies results: Strategic division of labor in challenge two showed smart training partnerships beat solo efforts
• Mental fortitude equals physical capacity: Jimmy’s ability to push through 50 push-ups while memorizing sequences proved fitness extends beyond muscles

The Bigger Picture Beyond Competition

Filmed at 1:13 a.m. on the Beast Games 2 set, this battle showcased more than athletic prowess. Both competitors displayed significant fatigue, jet lag, and less-than-ideal conditions—yet pushed through anyway.

Mr. Beast’s transformation from 40% body fat to competitive athlete represents achievable goals for millions of followers. His journey proves dramatic physical changes don’t require professional athlete status or perfect conditions.

Consistency, dedication, and progressive challenge led to measurable improvements in strength, endurance, and athletic performance. The close competition despite West’s training advantage validates that committed beginners can rapidly close gaps with experienced athletes.

West’s Instagram survived the photoshopped steroid threat, but both competitors won by demonstrating fitness accessibility. Whether losing 50 pounds like Jimmy or maintaining decade-long training like West, physical improvement remains available to anyone willing to commit.
