Pulling to the left!

[carnegie]

Hey everybody!

I do some pullups in my routine, because my chins are ok(around 15-20) but I can't even do 5 normal pullups. So I started with 3x3 pullups in every workout. Now my problem is that after the second pullup, I feel that my left arm is pulling "more" than my right arm(I am lefthanded!), and I feel my whole body pulling to the left and after I reached the highest point I can balance it out. Do you have any tips to avoid that. With only 3 reps at this time it shouldn't be that much of a problem, but after a certain I think that this could also result in a unbalanced body, and I want to absolutely avoid that!

Any recommendations are appreciated!

Thanks and bye
