“Jim Fixx was not available for comment.”
The guy who smoked two packs a day and had bad genes?
Moderation is key. Triathlons and marathons to me are the equivalent of running your car across country every week redlining the RPM.
Jim Fixx taught me to smoke cigarettes while I run. The nicotene enhances the exercise.
Other exercise enhancers I learned from the Jim Fixx fans is being a meth head, plus plenty of whiskey and vodka, drink liters of Coca Cola, and finally candy bars, plenty of candy bars make exercise efficient the Jim Fixx way.
