Hi all, I was wondering something in regards to moment arms. For example, in a smith machine squat where you have your feet in front of your body, you are applying force through your feet but the load is on your shoulders, so How do you identify the line of force in order to see the distance from the joints? Drawing an imaginary line from your feet (where you are applying force) or from your shoulders (where the load is)? Maybe it is a stupid question, anyway hope I made myself clear.
Actually, I do not like either the Smith Machine Squat, I was wondering about the torque itself, because as you said, the feet are in front of you, so you have another line of force and perhaps friction with the ground.
It would be great if Joe could do one of his ugly drawings to see this xD
