Going to the Bar
One of the most difficult movements you will be asked to do in a gym is the dreaded pull-up. As a trainer I have seen almost every possible variety of pull-up performed in a gym. Some were beautiful to watch and others, well, beautiful would not be the word used to describe them. You could always tell someone who used pull-ups in their fitness routine by the size of their back and arms. The ideal physique has always been described as a V shape, where the shoulders are wide and the waist is small, and the taper from the shoulders to the waist forms an impressive V. Pull-ups contribute more to that illusion than any other exercise.
