Training: Banish Man Boobs
Extra flab at the chest can happen with a dip in testosterone, but more likely it’s the result of putting on a few pounds. Combat either problem by adding tough intervals to workouts. Not only are they proven to raise T levels, “intervals are so intense that they continue to burn calories hours after you exercise,” says Martin Gibala, chair of the department of kinesiology at McMaster University. The key is making them hard enough to elicit that afterburn. To do it, pick any cardio activity, and alternate between a minute of work and a minute of recovery for 20 minutes. The first three sprints should be 80 percent of maximum effort. The second three, go for 85 to 90 percent. Crank to 95 percent for the next two, and make the final two bouts all-out.
