“Eureka!” is heard as scientists uncover new discoveries, the cry accompanied by a cartoon light bulb appearing overhead. If that cartoon scene holds a clue to fat loss, it may be the light cast by the bulb. Insane, right? Surely fat loss is not as simple as upgrading from 60 to 75 watts? Of course it isn’t, but there is a body of evidence suggesting that fat loss may be related to light exposure, more specifically, sun exposure.

Understanding the process involved is at first complex, but with a little effort, it becomes clear. In fact, don’t be surprised if you need to read this article two or three times to fully understand it, as it deals with true cutting-edge science. The process likely evolved eons ago, when man was just learning to walk upright and considered fire to be a message from the gods. Before the advent of air-conditioning, forced-air furnaces and grocery stores, mankind responded to the changes in season just the way animals continue to do today.

If you want a lot more thickness to your chest, nothing is going to beat barbell and dumbbell presses. As to how many you should do, it’s a matter of personal preference. These days I like to do an incline barbell press, a dumbbell press either on the flat or incline bench, and a machine press, but that’s now how I trained for most of my career. I had a partial pec tear two years ago while doing the flat barbell bench press, and it’s been out of my routine ever since. But if I had to say there was one exercise that gave me the most overall mass in my chest, that would be the one. Unless you have some serious injury that prevents you from benching, you should do it first and work hard on it for about 4 work sets of 8-12 reps (after warming up well, of course).
