To perform crazy plates, place a barbell on a bench and grab 2 light/purple bands. Take the bands and fold them in half twice. So that the band loops twice and the ends are touching. Slide this over the end of the bar. Visualize that with the band going through a plate. The first step might seem pointless but it will give you an idea as to how to set this exercise up. Take the band off the bar and run it through the center of a plate and back around OVER the edge of the plate and back through again. This forms the hanging plate portion. Slide that over the end of the bar and do the same thing for the other side and bench as you would normally except come down slowly. The movement of the plates coupled with the elasticity of the bands will greatly increase your ability to hold heavier weights and will help you with your stability.
