4. Bruce Lee – 9,600 searches per month
The father of martial arts and known for his relentless approach to training, Bruce Lee racks up 9,600 searches per month for people looking to emulate his workout style. Before his tragic passing when he was just 32, Lee possessed a leaner build compared to other actors in the list and was famed for his strikingly cut physique and year-round washboard abs. Lee is noted to have evolved his workouts throughout his career, making it difficult to pin down an exact workout routine. However, an excerpt from his notes revealed one of his earliest workouts that he performed three times a week included light squats, and 10 variations of wrist, bicep and triceps exercises to build up arm strength for martial arts.
