Testosterone is an interesting hormone. The more a man uses it, the higher his levels become. And the higher his levels become, the more he wants to use it. Exercise, especially resistance training like weight lifting, increases T levels. And then the increased T levels make a man want to go lift some weights. It’s a virtuous circle.
If gasoline in a car were like T in a man’s body, the more you drove, and the harder you drove, the more gas there would be in your tank.
But there’s not much gas in the tank of young men these days. The Cleveland Clinic and other researchers report that men today, especially young ones, have less T than ten, twenty or fifty years ago. Odds are, you’re not the man your father was.
Testosterone does more than make a man want to hit the weights. It also makes him happier, healthier, sexier, more muscular, more productive, and more reproductive.
