Maybe increase the weight by a pound or two to See how it feels, I bumped mine up quite quick because I wasn't feeling fatigue/soreness after the session.quickly after increasing the weight I could feel the difference, then just gradually
Add weight as your body tells ya. I'm on 6kg now and I reckon I'll be on it for 2/3weeks as I get adjusted. Hanging from other angles I used kingsnake pulley system to do SO and have a higher pulley to do like a 2 o'clock angel, check out his sticky in the hanging forum on the snake hanger, hope this helps
