Weight Training - Free Weights Vs Machines To Build Muscle & Strength

Weight Training - Free Weights Vs Machines To Build Muscle & Strength

Free weights provide a more complete workout. However, they also require more expertise in their use. When lifting free weights like barbells and dumbbells, not only is the prime mover or Agonist being worked but all the muscles responsible for stabilizing the joint. The result is to increase the strength of the stabilizer muscles. Greater care is required when using free weights. Improper technique can result in injury to the user or bystander if the weights are dropped.

It is important to remember to enlist the aid of a spotter whenever free weights are raised over the head. A spotter's responsibility is to insure the safety of the user during the execution of the exercise. The spotter must observe the condition of the user and try to anticipate exhaustion. The spotter must also insure that balance and an even lift is executed, that proper breathing technique is adhered to and that proper form is being executed by the user. A spotter's strength is not as important as his or her vigilance.

Machines provide a safer workout than free weights. Machines also specifically target a particular muscle automatically. It's harder to cheat during an exercise by incorporating unintentional muscle groups. However, since lateral movement is generally restricted, machines do not provide as complete a workout.

When lifting overhead with machines, a spotter is not necessary since the weights are confined to a rack and not directly overhead. Some machines are not adjustable for height or length of limbs on an individual basis. This can cause poor fit and even undue stress on joints when the supporting pressure incorrectly applied. The Biceps Curl and Triceps Concentration machines in many gyms are not adjustable and may cause undue stress on elbow joints instead of applying pressure to the back of the upper arm along the triceps.

In summary, free weights provide the best workout when a spotter is available and proper lifting technique is executed. In contrast, machines provide a better workout than could be safely achieved using free weights when a spotter is not available.
