Get in shape
No matter you are a defensive wrestler or an aggressive one, you need to be in shape. If you are not fit and agile, you will be overpowered pretty quickly. So, hit the gym regularly and maintain a healthy diet. Without doing these things, you should not get involved in any wrestling or street fight.
During a fight, you need to be alert all the time otherwise you will have to suffer the consequences. If your opponent is on the defensive, you might start taking him/her easy. This is the biggest mistake a fighter can make. Some experienced fighters use this tactic to deceive their rivals, so you should be aware of that.
Break the grip of your opponent
When your rival attacks, he/she will look to grab your shirt or collar in order to pin you down on the floor. Make sure you don’t let that happen, but if you fail to avoid it, break the grip of your rival by pushing him/he backwards. You can do this by grabbing the opponent’s sleeve or wrist.
Hold your opponent around the waist
Once you have broken the grip, hold your opponent around the waist, so that you can force him/her down. Position yourself in a bear hug, so that the other person cannot move freely.
Kick your opponent down
Now, you need to kick your opponent on the Achilles tendon in order to destabilise him/her. Once he/she is off balance, you can easily finish the move off by bringing the attacker down.
Complete the arm bar
Finally, you can complete your move by standing over your opponent’s head and throwing yourself into the arm bar.
