BUTT DON'T BELIEVE ME, READ!
I know you thought I was joking, but most professionally, you will need torque; The rest is meant to get your attention, to the torque of course...what else???
Torque is a force that creates circular movement, known as rotation. Torque is also one if not the most utilized force to create skeletal movement in the human body. This is true since the major joints of the skeleton are structured to have bones move in a circular way one compared to the other. Since torque is a force that creates circular or rotational movement, it is required for human movement.

Torque is the mathematical result of multiplying a force applied to a rotation allowing axis (joint) by the distance between the force application and the rotational axis (joint). the greater the force applied, the farther away from the axis that force is applied, and the more suitable the joint is for rotation, the greater the torque produced.
It is important to understand that while the movement described in a joint might seem linear, the actual movement of the bones themselves within the joint, is circular. For example, flexion and/or extension of the elbow make the the forearm move through the sagittal plane of movement is a straight line, yet analysis of the movement of the bones involved, is not linear at all.
The joint within the elbow complex that allows flexion and/or extension is a hinge joint, that as all hinges, are built to have one part move in a circular motion compared to the other. Obviously, actual rotational movements of the skeleton are the result of torque forces applied. Diagonal movement in the body requires slight rotation, thus requires torque as well.
In summary, though skeletal muscles pull straight on a tendon, that pulls straight on a bone, and although tendons connect in a straight line onto bones, the relative movement between the bones is circular. Circular movement = the need for torque as the mechanical force creating it. Thus, the next time you go wild and twerk it, remember: you had to torque it first.
