Jon Call “Jujimufu” Absolutely Crushes a 161-Pound Preacher Curl PR

A new preacher curl PR is only the tip of the iceberg when it comes to Jujimufu in the gym.

Written by Robert Zeglinski Last updated on Dec 12, 2023

There are lifters with incredible all-around strength and an adventurous spirit, but few can match the energy of the incomparable Jujimufu (real name Jon Call). An absolute storm of power and athleticism, Call never says no to a fun and seemingly impossible lift. He’ll push himself with any of the compound exercises like a bench press, then turn around and destroy inverted rope rows while draped with countless chains.

One of his latest feats seems to indicate he’s leaving no weight uncurled when working out his arms.

On June 30, 2022, in a demonstration of his biceps strength, Jujimufu shared a video where he completed a 161-pound preacher curl for a new personal record (PR).

At the time of this writing, Jujimufu has approximately 1.6 million followers on his Instagram profile. According to U.S. Census data from 2020 that World Population Review has gathered, his following would be enough to populate the sixth-biggest city in the United States, surpassing Philadelphia, Pennsylvania.

That metropolis of people gets a perpetual front-row seat to all of his obstacles and achievements.

Preaching to the Choir

Jujimufu’s training with a one-rep max preacher curl could say a lot about his near-term goals. The athlete will compete in the 2022 National Physique Committee (NPC) North American Championships. Those will occur from August 31 through September 3, 2022, in Pittsburgh, PA.

The preacher curl is a popular bodybuilding arm exercise. The idea behind it is that curling with your arms sitting on an angled pad, both removes any tension-breaking momentum and creates a more significant stretch in the muscle. In general, studies show performing anywhere from one to five heavy reps is a good range to increase strength on a preacher curl. (1) There’s something to be said for anecdotal evidence, and Call’s arms look jacked. He didn’t reveal his training split, so this one-rep max preacher curl is likely a one-off attempt.

Jacked biceps with a quality pump will undoubtedly be a part of any hopeful victory for Jujimufu at the North American Championships. His planning and strategy may have taken part of that into account.

Balanced Experience

Jujimufu does show off a more “traditional” lift now and then. In addition to previous bodybuilding experience and ambitions, he’s also competed as a powerlifter before. According to Open Powerlifting, the athlete’s best powerlifting result is a podium finish at the 2020 World Raw Powerlifting Federation (WRPF) Hybrid Showdown II. Meanwhile, per NPC News Online, his top and only bodybuilding result was a fifth-place finish in the heavyweight division at the 2021 NPC Worldwide Amateur Olympia.

That dynamic athletic background should give him Jujimufu a reliable base of strength on the squat, bench press, and deadlift movements. In addition, he might have a more expansive knowledge of nutrition and different training disciplines.

Here are Jujimufu’s powerlifting competition personal bests:

Jon Call (Jujimufu) | Competition Personal Bests

  • Squat — 305 kilograms (672.4 pounds) | (W/Wraps)
  • Bench Press — 189.6 kilograms (418.8 pounds) | (Raw)
  • Deadlift — 302.5 kilograms (666.9 pounds) | (Raw)
  • Total — 787.8 kilograms (1,736 pounds) | (W/Wraps)

What’s Next

It can prove difficult to predict the next steps of athletes like Jujimufu, who seems open to trying anything under the sun. Whatever lift Jujimufu shares on his social media has an appearance of random, spur-of-the-moment, and creative thinking. In terms of official competition, Jujimufu hasn’t competed in a powerlifting contest since February 2021 and a bodybuilding contest since October 2021.

Aside from the upcoming NPC North American Championships, it’s unclear what individual feat Jujimufu will tackle next. He might prefer it that way.
