Many begin to practice in the gym for the totally wrong reasons.
They draw them various complexes of whatever they say about the improper exercise of the exercises and putting larger weight on the devices than those that their body can withstand.
That is why it is most important to begin with yourself to clarify why you are training and what your goal is actually ...
If it's just looking at the mirror and takeing photos for the instagram and others social networks, better leave the gym immediately so that there are no injuries and some unintended consequences ...;)
Go slowly according to the possibilities and listen to your body, your one will never agree ...
Step by step and the result will not be missed, it will not happen in 2 3 weeks, but in the end you will reach the goal!
