Endomorphs. They usually have a shorter build and they do gain fat quickly. This is how endomorphs are short and stout. They have heavy arms and has strong muscles that are located in the upper leg.
I believe it would be 60 minutes and 5 to 6 days a week because you need a resting period.
So the fat doesn't melt. Fat=flavor.
OSHA (one part of a Personal Fall Arrest System) requires workers to wear a full-body harness, when they are working on a suspended scaffold more than 10 feet above the working surface, or when they are working in bucket truck or aerial lift.
