Langer Name Meaning. German, Dutch, Danish, and Jewish (Ashkenazic): nickname for a tall man, from an inflected form of Lang. According to Gottschald, in the Franconian dialect of German this was also a term for an unskilled laborer (more fully, Handlanger).
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.
But most importantly, all three aspects of muscle growth are interrelated. Muscle tension with heavier weights can cause fiber damage that allows for swelling and metabolic stress to occur. Muscle tension with lighter weights and more time under tension triggers metabolic stress, during which blood canât escape your muscles quick enough, and helps promote growth. And then tension with moderate weight for more reps or different exercises ignites both metabolic reactions and damage.
