Muscle is the quickest way to a hot, healthy body. If you just go on a diet, or if you just
diet and do cardio, you may end up a little thinner, but unfortunately, you’d have to work
so much harder to keep your weight down. Muscle is the only think that speeds up your
metabolism so that you can consistently burn calories for hours and while resting.
Myth #1: Longer Workouts = Better Workouts
With most goals exercise quality is more important than quantity. Smart exercise will always take precedent over long exercise. Each workout has 2 primary variables: intensity and duration. Try to workout at a certain intensity so the duration is limited.
Not controlling your workout intensity and spending too much time in the gym is actually bad for your body because your body will produce excess stress hormones which will hinder the recovery process.
