​

Purpose: Compared a conventional pull-up and chin-up with a rotational exercise using the Perfect Pull up device with twisting handles.

​

Conclusions: No differences were detected between the Perfect Pull up device with twisting handles and the conventional pull-up and chin-up exercises. The Perfect Pull up rotational device does not appear to enhance muscular recruitment when compared to the conventional pull-up or chin-up.

IN PLAIN ENGLISH: No magical exercises exist. A lot of things work provided you work as hard as possible.
