You’ll remember this from grade school: An object at rest tends to stay at rest, while an object in motion tends to stay in motion. It’s Newton’s First Law. In fitness terms, this means that the more you exercise, the more your body wants to exercise.
“Our bodies were created to move,” says Sally Edwards, MS, founder of Heart Zones training company in Sacramento, Calif., and author of The Heart Rate Monitor Guidebook to Heart Zone Training (Lifestyles 4-Heart Press, 1999). “When you don’t move, you’re violating the principles of physiology.”
Part of it is a state of mind, of course. When you stick with a routine for more than a few weeks, working out becomes a habit. And as you begin to see results, your self-confidence and motivation build, making it easier to keep moving day after day. But there are also plenty of physical changes that contribute to the cumulative it-gets-easier effect. Your heart pumps more efficiently. Your circulation improves. Your muscles take longer to fatigue. Your body may get lighter, more compact and easier to move through space.
“These are tangible rewards that can propel you forward in your fitness, making it harder to revert to your former sedentary self,” says Rachel Cosgrove, Santa Clarita, Calif.–based trainer and author of The Female Body Breakthrough (Rodale, 2009).
Pay attention to those payoffs, and before long you’ll find it tougher not to exercise.
