What happened to muscles when you do weightlifting?

Answer 1

your body makes more muscle tissues, which makes you "Ripped" Where ever your working towards. When you start to feel a pain, it's because your body releases lactic acid when your not getting enough oxygen into your body when your working out. When this occurs, you should take a break and do some breathing exercises.

Answer 2

The exact details are not yet known. Basically, however, resistance stresses a muscle so much that it requires repair. Therefore, when you lift weights in the gym, you are not actually getting stronger or bigger muscles; instead, you are breaking your muscles down.

With proper rest and nutrition, however, your body will repair your muscles so that they are stronger and sometimes larger than they were before you trained.

Therefore, rest and recovery are as important as training. Without sufficient rest and recovery, you will become overtrained, which may actually decrease the size and strength of your muscles as well as weaken your immune system.

Answer 3

Weight lifting makes your muscles stronger because they adapt to imposed demands. If you lift very heavy weights, your muscles will not get very big but if you lift lighter weights within the 8-12 rep range, your muscles will get bigger over time. Your muscles improve their strength and tone and size by way of adaptation by something called supercompensation.

Answer 4

This is a question with varied answers. If low weights and high (or many) repitions are used, a person will lose fat and muscle growth will be comparatively slow-repitions of 20 or above with 30 second rests in between sets should accomplish this. Medium weights with median repititions (12-18 repitions with 1.5 minute breaks) will tone muslce. That is to say, bodybuilders often will tone their muscle and make it more defined. High weight with low repititions (2-10 repititions with 3 minute breaks) will result in muscle size and strength and you will be seeking pure powerlifting status by doing so.

Answer 5

If you eat healthy and lift weights and give your musels enough time to full rebuild you should start gaining musels and losing fat.
