I can think of more than a few occasions where boxers were told not to have sex 48 hours before the fight outside of Rocky lol. I remember the build up to one of jeff laceys fights when he was an up and comer and I believe it was HBO that followed him around and you heard his trainer tell him the same. Pacman is another big name that is said to practices the same. From my understanding it all has to do with a persons "Psyche". Psychologically it is said by some that after sex you will be less competitive or less motivated to compete. Also, it is not just your hand that is getting an extensive work out by masturbation but your heart as well. While it is not exactly working out, I believe your heart rate will still rise 3/4th's of what it would had u been running on a treadmill. Run a mile. clock your time. the next day, choke it 5 times then run your mile. see results lol. Also remember masturbation is "simulated" sex. So I imagine the results will be less with that than the real thing.

There are plenty of benefits of sex also. Increased endorphins which help deal with pain and give a feeling and sense of well being and contribute to ones ability to BOND. plenty of pro's to go with the con's. So i'm on the fence with the subject. I will just say to much of anything is not good in most cases.
