Be Physically Fit
You need to eat healthy, sleep well and take good care of your overall health. These are important factors for any wrestler in order to be successful. You should also hit the gym more often and make sure that you do the right workouts to build strength and muscle. Having a personal trainer at the gym can also be useful in moving in the right direction.
Along with a strong body, you should have a strong mind as well. Wrestling is about physical strength but the winner is often one who can use his mind to conquer the opponent. The wrestlers try to intimidate others by their bodies with big talk and big acting. If you can down play these and can pick the soft points of the opponent, you can be successful. Also, knowing when to make the right move helps in winning.
Watch the videos of the pros and see how they do it. Learn from them and try to do similar moves. Also, joining a training school is not a bad idea as well. You can learn the craft from the professionals and hone your skills.
You can start at an amateur level and start running the craft. Initially you are likely going to have a tough time but with every match, you will learn something new. This is a massive learning curve that will help you when you reach the big stage.
Build a Persona
As you play more matches and perform well, people will start noticing you. Have an aura around you. Pick your specific kind of dress code and have you punch lines that you always like to use. This will help you in getting even more fame and your fans will start acting in that manner as well. Promoters need someone who can be likeable for the crowds and if you can get this right, you should have some knocks at the door. This will be your ticket to the big stage.
