When you skip weights you miss out on the ultimate fat burner! Muscle boosts your metabolism which keeps you lean and sculpted. Weight training is crucial to building and maintaining muscle. You will truly lose it if you don’t use it! To stave off muscle decline as we age-you have to carry a heavier load. Lifting heavier weights is far better for you than lifting lighter weights. You do not have to do endless reps to gain a benefit.(Endless Reps=Overuse Injuries.)10-15 reps with weight that is heavy enough to barley finish the set is perfect.(Both men and women can lift heavy weights-Men will gain size because of their levels of testosterone, women do not have this issue. Women get bulky when there is too much fat on top of their muscle.) Muscle accounts for about 1/3 of a woman’s weight so it has a profound effect on your metabolism. Muscle chews up fat calories even when you are not in the gym!!
