So I have some of questions on PE4
1. Are you supposed to be as tall as possible when doing this exercise?? or is it fine to not extend your arms out to be tall?
2. How much weight are you supposed to use on the bar? can you start without any weight and just a wooden stick in case the exercise is too difficult?
3. Once you concentrate on pressing your core to the ground and your upper back flat on the floor doesnt the exercise become exactly like(and hence really difficult) the most difficult HBH??
Thanks in advance
