Free Weights or Machines?

Ever wonder why you can lift more weight using a machine than with a dumbbell?  Free weights force you to recruit more muscle fibers to help stabilize the muscle that is doing the lifting.  Machines provide stability for you.  A recent study done by Scott Lyons, PHD associate professor of exercise science at Western Kentucky University in Bowling Green stated that exercisers were able to lift about 25 percent more weight when using machines vs dumbbells.

Using free weights activates more core muscles as well other muscles to stabilize the body.  Standing offers even more muscle recruitment.  We don't go to the gym to sit!  Get up and crank it with free weights!!!!
