Her are they
Now, there are several forms of lifting.
.. Isotonic, auxotonic, isokinetic, and isometric. Here is a brief defination of all.
Isotonic - where there is constant tension during the lift
isokinetic - constant velocity (speed) in the lift
isometric - there is no change in muscle length during the lift, static
auxotonic - changing tensions caused by altered velocities and joint angles.
