Quick Fit Tip - The Benefits of Strength Training

There are 3 laws of physics: Inertia - a body at rest stays at rest unless acted upon by an outside force; Force = Mass x Acceleration; and for every action there is an equal and opposite reaction. These apply to strength training: a weight remains at rest until acted upon by a force. Muscles generate the force to move a weight. The act of lifting weights can improve muscle strength and appearance. Learn the benefits of strength training and how to add it to your workouts. Learn more about your ad choices.
