Has this ever happened to you?
Keeping this day in mind a few months later you finally have enough energy to bust out the scale and weigh yourself. And to your surprise you weigh several pounds less than you usually do. Are both phenomona linked? You bet.
Spring has magical effects on a body's chemistry. Its pychological effects are powerful. The most memorable warm day of early spring was a day in March of my last semester of high school. By the time the 2:30 bell rung people were going nuts. Yelling, running, wrestling, and slacking off were my activities for that day. By June of the same year I noticed about a ten pound drop in my total mass. A change of season definitely can change the homeostatis. Body switches to a more agressive mode, probably a remenant of ancient cycle of fattening up for the winter and mating for the summer.
While professional bodybuilders chose to use steriods and fat burners to do their dirty work, they still follow the ancient cycle- fall/early winter fatten up, early spring/summer chisel fat. With the knowledge of this cyclical pattern of weight, bodybuilding can be put on another and more natural level.
During the fall and early winter diet should not be watched as closely. One should still keep track of his or her protein, making sure that the person gets enough. It should slackened to the point where moderate weight gain is permitted (5 to 10 lbs,tops). Exercise rountine also changes from the summer's high-volume aerobic, moderate weight and number of reps and sets to low-volume aerobics, high weight and number of sets and low reps. This switch demands more protein and the excess food ensures the needed calories and extra protein for muscle mass gain. Spring and summer diet and rountine is simply reversed- calories are kept at a minimum (meaning eat only when you're actually hungry) while keeping protein levels high to maintain muscle mass.
