It is not completely clear how Herschel Walker structured this workout throughout his day. In his video, he makes mention of performing them during commercials. Other literature suggests he started in the morning and finished at night. Regardless, there is probably no human on this earth who could perform all of those repetitions in one set.

Herschel Walker on Howard Stern - "I Sleep Four Hours a Day and Only Eat One Meal a Day"

    Howard asked Herschel what it means when he says he only sleeps 3 or 4 hours a night. Herschel said he sleeps 4 hours at the most and he only eats one meal a day. He said he doesn't eat meat anymore even though he owns a meat company. He eats salads and soup and bread. He said he does that late at night when he's going to bed. He said he's been doing that for over 20 something years. Howard asked how many calories he takes in. Herschel said he doesn't worry about that so he doesn't know.

    Howard said he read that Herschel once played Russian Roulette. Herschel said he wrote a book and talked about that in there. He also talked about his multiple personality disorder. Howard explained what Russian Roulette was and Herschel said he did that over six times. He said he was alone when he did it. He said he thought of it as a competition.

    Herschel said that his marriage ended because of that stuff. ... Herschel said he forgets some things like getting the Heissman trophy.

Walker is also intriguing for being one of the few pro football players to become successful without the use of free weight training. Rather than a heavy weight room regimen, Walker used bodyweight exercise, calisthenics, and conditioning, as well as martial arts training. He remains to this day an oddity in the pro football world. He has been said to do thousands of pushups and situps daily, rather than lift weights[citation needed] For the past twenty years, he claims to sleep four hours a night and only eat one meal a day during the evening, which normally consists of a salad, soup and bread.[citation needed]
