Fat Vs. Muscle – We hear it all the time… “I’m working out less and my muscle is turning into fat!” This is one of the biggest myths in weight training. Muscle and fat are completely different types of tissue and can’t magically be changed. Muscle shrinks (atrophy) when not stimulated, so your muscles may seem softer. Compounding the problem, most people don’t lower their calorie intake to match their now lower energy needs. The result is less muscle mass and extra calories being stored as fat which creates a shift in your body composition.
