Hey Christian thank you for answering!
You're right, I will start the bar right above the knee in the future. This is just wasted energy. I didn't know my grip is narrow enough, I had middle fingers on rings, I guess I can go with thumbs on rings?
Lastly, how can I make my extensions better? I think triple extension but it doesn't work too well. The touchb the ceiling to your head is good though. Is 5*5 effective here on SGHP, or should I work up to max triples and singles?
