We have discussed alignment for free cruisers weights, but as a final note, I would like to discuss cruisers machines. Every joint helps define a lever on your body. There is a concept known as "open lever" and "closed lever". As an example, when cruisers you work your chest through the full range of motion, you open the lever. Once your upper arms go beneath parallel, tension is REDUCED in your chest and taken up by your triceps and other supporting muscles. If you stop at parallel, you actually keep more tension on the chest and the lever is "closed". This concept applies to machine workouts as well. With machines, joints again play an important role. When you are getting into a leg extension machine, your knee joint should align with the "joint" on the machine - the pivot point. The knee should not be forward nor backwards of this. When the knee is properly aligned, your back should be flush against the chair - this is how you adjust the chair forward or backward.
