Japanese fitness enthusiast Tasuke, now 44, completed a three‑year daily workout inspired by the anime hero Saitama, shedding roughly 13 kg and ticking off marathon, ultramarathon and Lake Biwa ultra‑distance goals. The feat, achieved despite a COVID‑19 infection, broken toenails and a collision with a car, has sparked both admiration and caution among health professionals.

Daily Grind: 100 Push‑Ups, 100 Sit‑Ups, 100 Squats and a 10‑km Run

From April 2023 to April 2026, Tasuke performed the exact routine described in the manga: one hundred repetitions each of push‑ups, sit‑ups and squats, followed by a ten‑kilometre run every single day. he began the challenge at 41 years old, standing 175 cm tall and weighing 74‑75 kg. By the end of the third year his weight had dropped to 62 kg, while he retained enough muscle mass to complete a sub‑four‑hour marathon, a 100‑km ultramarathon and a 200‑km circuit around Lake Biwa.

Setbacks on the Road:COVID‑19, Broken Toenails and a Car Accident

According to the source, Tasuke’s consistency was tested by several serious setbacks. A COVID‑19 infection in late 2023 forced him to train while ill, and a broken toenail in early 2024 threatened his running form. Most dramatically , a vehicle struck him in mid‑2025, yet he did not miss a single training day. These incidents illustrate the extreme physical toll of the regimen and raise questions about long‑term health sustainability.

Expert Warnings: Overuse Injuries and the Need for Rest

Fitness experts cited in the report caution that the volume of daily work exceeds what most beginners can safely handle. They note that repetitive high‑repetition movements can cause joint stress, muscle damage and lower‑back pain, especially when sit‑ups are performed without proper technique. The specialists recommend incorporating rest days, varying core work with planks or bridges, and seeking professional guidance to avoid chronic injuries.

Comparative Cases: Li Shuangyong’s 1,000‑Day Marathon Attempt

The article references a Chinese counterpart, Li Shuangyong, who pursued a similar 1,000‑day daily marathon schedule with the aim of setting a Guinness World Record. while both men share the same anime‑driven motivation,Li’s plan focuses on marathon distance rather than the mixed‑modal routine Tasuke followed, highlighting a growing subculture of extreme, character‑inspired fitness challenges across Asia.

What Remains Unverified: Long‑Term Health Outcomes and Official Records

Two key points remain unclear: first, whether Tasuke has undergone any medical assessment to confirm the absence of lasting damage from his three‑year grind; second, whether any official body will recognise his achievements as a record, given the lack of formal verification. The source does not provide confirmation from a sports federation or medical professional, leaving these questions open for future investigation.
