One of the most common questions of people new to weight training is the difference between free weights and resistance machines. The truth is, there are advantages and disadvantages of both. However, both will promote an increase in overall strength. This article will help you decide which form of training is right for you.
Free Weights.
Free weights are proven to give quicker strength than the corresponding machine. Unlike machines, they force your body to incorporate extra muscles to stabilize the weight as you lift it. They are also a lot more versatile, to do the number of exercises you can do with one set of dumbbells, you would need more machines than most gyms have available. The motion used with free weights more often resemble the motion you are to use in athletics. Being 6'6" tall, I have found a lot of machines don't allow a large enough range of motion for me to get as much out of the lift as I would when using free weights.
Although free weights have plenty of benefits, there are also some disadvantages to consider. When training with free weights, not using the correct form during a lift greatly increases your risk of injury. Lifts like bench press, squats, and cleans require you to have a spotter, not everyone who wants to workout has the luxury of having a partner everyday. Free weights are harder to isolate one muscle, since they require more muscles to perform the lift. When becoming fatigued during a lift, it is very easy to start using your momentum to get the rep, rather than a steady contraction of the muscle.
Resistance Machines.
When using a weight machine, it is much easier to isolate a target muscle because they provide no room for error in your form (making them a much better choice when rehabilitating an injury opposed to free weights). Machines are easy to use, which make them very appealing for beginners. For those of you working out at home, machines take up a lot less space than a squat rack or a clean station. If you are new to the weight room, I recommend starting out on resistance machines until you are comfortable with your form and strength.
Although machines are very safe compared to free weights, they also have a lot of disadvantages. They do not offer much versatility (most machines only offer one exercise). A lot of people find that they do not offer enough weight for core lifts (bench press, squats). If you are looking for a weight training program at home, machines are much more expensive than free weights and aren't nearly as versatile.
Overall, I have found that I get the most out of free weights in almost every way, but still use the machines when having trouble targeting specific muscles. I believe that having a variety of both resistance machines and free weights in your workout will give you the best results. But, like I said before, anyone who is new to weight training should start with the machines until they are comfortable with their form.
