Muscle does not weigh more than fat, any more than lead weighs more than feathers. A pound is a pound is a pound. Where the misunderstanding often comes in is that muscle is much more dense than fat, so that, by volume, it seems to weigh more. That is, a pound of muscle occupies less space than a pound of fat. In addition, because a pound of muscle burns more fat than a pound of fat, even at rest, by increasing your lean muscle tissue mass, you're helping your body burn more calories. But back to your question.
Latissimus dorsi and erector spinae-these muscles are your lower back muscles, and are particularly prone to muscle knots. Semispinalis capiti-the muscle that runs to the base of your skull. Muscle knots here are the gift that keeps on givingâthey can cause migraines and fatigue. Gluteus maximus, medius, and minimus-pretty much each and everyone of your derriere muscles can give you a nice muscle knot and a limp. Ouch!
