An easy way to start weight training is to use the weight machines available in most gyms. These are user-friendly, have you move your body in a logical path, and usually have instructions telling you how to use the machine. They are good exercise — they move your muscles, get your heart pounding, and generally force your body to work off some calories and fat. However, if you are serious about weight training you should look into a freeweight training program.
Freeweights roughly divide into two categories: dumbbells and barbells. Dumbbells are weights that you hold in one hand, while barbells are bars with weights on either side of them. Obviously, dumbbells are going to weigh less than barbells for similar exercises because you need to hold two of them.
Weight machines do help you get started on resistance training programs, but they have some major drawbacks. For one, they are machines in the rawest sense of the word. They use pulleys, wedges and inclined planes to help you get the weight where it needs to go. This means that you are not really doing all of the work yourself, but rather are helping the machine do the work. This is profoundly different from moving a weight yourself.
Another problem is the fact that the range of motion is fixed. When the angle you move your weights at cannot change, your body does not need to engage stabilizer muscles. This means that the workout is not as good with free weights — you may be working the “focus” muscle (as in bicep curls), but you are not working any of the auxillary muscles. This means that it may take two or three different weight machines to do the work of one barbell exercise or dumbbell exercise. This is not very efficient, and it makes for longer workouts.
So speak to a personal trainer or someone else with intimate knowledge of weightlifting about a free weight program. They may be intimidating to start out, but once you’ve mastered the form you’ll wonder why you ever used machines in the first place.
