While there are certain flaws in this argument it should be used to reasses the myth versus reality of the whole situation, as should this portion:
Numerous persons have stated that Bruce Lee possessed an incredible amount of strength. Based on his exercise program, it appears he was of below-average lower body strength. According to the strength training program Lee used during 1965 (Lee, 1989), he performed squats using 95 pounds with 10 repetitions. This would equate to an estimated 1 repetition maximum (1RM) of 130 pounds (Wathen, 1994), which would place him below the 25th percentile for the 121-140 pound weight class among adult males (Hatfield, 1993).
This type of estimation for the 1 repetition maximum is standard among athletic trainers to assess the strength level of a wide range of athletes, both professional and amateur.While some chart estimates may vary slightly from one to another, most are within approximately 10% of one another.
Some readers, who are accustomed to viewing Lee as possessing epic strength, may assert that Lee probably was not using his maximum ability at that time. It is therefore noted that this regime occurred prior to Lee's well-known back injury. Furthermore, if Lee was capable of performing the squat exercise with more than 95 pounds for 10 repetitions, one must question why this was part of his established routine or, alternatively, why he would be committing himself to a method of underachievement by using too low an amount of weight to stimulate the greatest strength gains possible.
As with any arguments flaws and evidence must be equally examined. The main problem with all of the arguments presented is that they are based on anecdotal reports (though these are ones typically given by Lee, Lee's family or Lee admirers). As has also been reported Lee himself resisted efforts to quantify his actual abilities.
...while Funakoshi admonishes martial artists to render honor to their families before refining themselves, when Bruce Lee did refine himself physically it was not in a wholly honorable fashion. In addition to the prescription medications Cortisone and Dilantin, he is also reported to have used anabolic steroids and diuretics to achieve his physique (Beeckler, 1996).
