About muscles in our body

• All of the 639 muscles in the human body can be
  trained.
• Every single muscle in our body cannot be trained
  because there is an interaction of many different
  muscles with certain movements.
• Distinction is made between muscles that can be
  controlled at will and those that are primarily
  involuntarily active.
• The heart or intestine consists of so-called
  smooth muscles and this works involuntarily as
  long as you live.
• when you exercise, the heartbeat increases and
  the heart muscle is actively stimulated beyond
  its normal work routine. No matter where the
  stimulus comes from, usage trains the muscles.

Muscles consume more energy than other body
structures.

• Muscles are directly connected to the bloodstream
  compared to adipose tissue.
• You continuously consume energy because muscles
  have to be kept warm. However, this energy
  consumption is not as high as some think
• The body needs about 100 kilo-calories a day to
  keep one kilogram of musculature warm. This
  energy can easily be provided by consuming a
  medium-sized orange.
• To lose one kilogram of body fat, a man weighing
  80 kilograms would have to burn or consume about
  9000 kilo-calories by running 15 hours at a time

Muscles only grow when you use them.

• The muscle mass of every healthy person increases
  about thirty times and the quality of the muscle
  varies with not only the general growth but also
  with its use.
• Hypertrophy training help the muscle fibers
  become thicker and loaded with up to 85 percent
  of their maximum performance.
• It is possible to increase the number of muscle
  fibers. Such enlargement of the tissues is called
  hyperplasia.
• happens especially with eccentric loads which
  means the muscle is shortened and at the same
  time stretched against the resistance.

Muscles grow during training breaks.

• Training means to break the muscle fibers.
• The adaptation and regeneration of the muscles
  always happen during the breaks.
• The breaking and regeneration of the muscles is
  the basic requirement for improved muscle growth.
• For this reason, you should plan 48 to 72 hours
  for regeneration after intensive training.

6
Muscles grow with a high-protein diet.

• Greater protein storage occurs only in an
  exhausted muscle. If the body has no protein,
  then none can be stored.
• essential amino acids are particularly important
  for muscles and are not made by the body itself
  and should be consumed daily.
• more you train, the more essential amino acids
  you require and you have to increase the supply
  by consuming more protein.
• Within 30 minutes after training. It is even
  better if the muscle is provided with some
  protein beforehand like in the form of egg or
  dairy products.

7
Everyone gets sore muscles after overexerted
training.

• Sore muscles are a normal physical reaction and
  not a disease and therefore not dangerous
• Sore muscles develop in response to minimal
  damage to muscle tissue.
• The healing mechanism of the body starts working
  when muscles are overused.
• Professionals also get sore muscles if they have
  not prepared certain muscles sufficiently for the
  stress.
• You can have prevent yourself from having sore
  muscles by preparing the muscles for extreme
  workout through pre-workout.
