sorry i am just going to have to be crude with this.
If you keep on training your right arm more then your left all you are going to do is make people think you are a world champion w@nker you only uses his right arm.
Do the same amount of reps for both, starting with your weaker arm. If you don't one arm will always be much stronger and bigger then the other, which is never a good look. Also buy some heavier weights. Doing 100 reps i on the light weight isn't going to really achieve much. Also how often do you this routine and do you do any other exercises
