Also, if the machine has a seat belt, "buckle up." When not firmly belted to some machines, the lifting position can shift causing a redirection of force from the intended muscles to other muscle groups, particularly those stabilizing the back.

• This defeats the purpose of the exercise and can cause injury.
  
  Regarding breathing, generally tell participants to maintain their normal breathing pattern while lifting. However, as exertion increases, they should be taught to exhale during the more strenuous part of the exercise, and inhale during the less stressful phase.
