Hey bro's a lot of guys on hear want those big guns to show off. Well I'm sure someone else has done this but if you haven't and you wanna try and get your arms to grow give it a shot. A lot of people realize that arms, legs ext... need a lot of muscle stimulation to grow. This is because we use them every day so they are used to working hard with a lot of repetitive movement and motions. Anyway this is what I've been doing and it seems to work. At the end of your workout after you've done your heavier weights on the gun, try this to finish them off. Instead of 21's try 60's for three sets. Now do these light as fuck, remember this is just to pump those bad boys full of blood and stretch the facia. It's the same concept as 21's just instead od 7reps on each movement do 20. I promise you will be pumped as fuck and sore as he'll the next day. Do three sets for a total of 180 reps. I use a 20 pound easy bar to due these, Yes that's all you need at the end of a workout. The point of this is to stretch your facia and shock the he'll out of your arms. If you go to heavy YOU WILL GET INJURED. Try these out and tell me what you guys think of them. I personally have noticed my guns grow Wich is hard cause of my arm length and height. Let me know what you guys think.
