Free Weights or Machines
Is There a Difference Between These Modalities of Lifting
Can you expect to get different results from your work out when using free weights vs. machines? Your goal should determine which modality you use.
There is some question as to whether machines offer the same benefits as free weights when lifting. Some people believe there is no difference between the two while other believe strongly that there is indeed a difference. While both forms of lifting offer benefits, the discrepancy arises from a belief that machines don’t require the same amount of stabilization necessary when using free weights.
The stabilization argument is a valid argument and one of the major differences between the two forms of lifting. The ideas expressed here are not that one form of lifting is better than the other but rather that both have there place in the fitness arena. As an advocate for fitness any form of movement would be better than none at all. Since this discussion is however based on the comparison of the two forms and which one is better let’s take a closer look at each one.
Machines are easy to use, they do not require the same amount of stability free weights do. Machines generally require the user to select weight by inserting a pin in the appropriate resistance level of a weight stack and begin moving the weight along a predetermined path, based on the design of the particular machine. The predetermined path of movement doesn’t require much stabilization so you don’t work the same volume of muscle you would using free weights. This is conducive to a quicker workout since it doesn’t require the adding or removing of weight plates.
Free weights on the other hand take more time to work with because you have to load and unload the plates based on the desired resistance level. If you are lifting heavy you will need a spotter or spotting device to ensure proper technique and safety. When lifting free weights you recruit many more muscle (fibers) groups due to the simultaneous control and stabilization required. It is this stabilization (muscles recruited) aspect that makes free weights superior to machines. Bodybuilder utilize free weights for this very reason, but specialized machines are also used from time to time for change of pace and isolation work.
The bottom line is this: you can reap distinct benefits from each form of lifting. Free weights will build muscle faster and efficiently, but machines do offer fitness enhancements as well. Don’t give up on machines if your goal is to improve your fitness level, machines will allow you to achieve this.
