Free Weights vs Machines – Is One Really Better Than the Other?

I wanted to touch on the free weights vs machines debate in this post because the switch from “gym workouts” to “home workouts” means you might need to make use of alternative exercises. That is if you’re using a pre-planned routine to get in shape.

When I first started my home fitness quest I did a lot of research to find suitable solutions to replicate the same type of muscle stimulation. I actually did a lot of research to replace the typical exercises in my workouts.

I came away with a strong opinion, and resolve, that free weights were the best solution. But, can ideas and opinions change?

Free Weights vs Machines

For some, this is a clear black and white debate. One has to clearly be better than the other. The common rule is to never talk about politics or religion in the work place. If someone ever asks you the loaded question, “Free weights vs machines, which one’s better?” Unless you want an argument, don’t fall for it!

The Pros and Cons of Choosing Your Poison


As time went on and I started including more pieces of equipment into my garage setup, my definition of “machine training” changed. I use a cable setup in some of my routines, and while it doesn’t weight a ton it is still technically a machine.

You might expect that I’d be all about free weights. It is, after all, how old school training was done. With respect, how could I say those classic bodybuilders were wrong?

I do want to emphasize that while free weights actually perform better when building muscle, machines are a great option for beginners. Even though machines do limit the range of motion, they generally are better at reducing the risk of injury (by pushing yourself or by dropping the weight on yourself) and will foster proper form better than free weights can in the beginning.

Here’s my cue to segue into the talking points for each side of the free weights vs machines debate.

 

Free Weight Pros:

  • You get more output from the muscles to complete an exercise. Far more stabilizing muscles are engaged in each exercise.
  • Movements replicate “real life” needs.
  • A hell of a lot cheaper.

Free Weight Cons:

  • Using proper form is critical staving off injury.
  • Unless you have a quick changing system on your barbells or dumbbells, switching weight can take a bit of time.
  • Sometimes experience is required.

Machines Pros:

  • As stated above, there less chance of injury when using machines in a workout.
  • Generally, machines are easier-to-use.
  • There’s a lesser amount of strain on the joints (e.g. a press machine will not stress the shoulders as much as it’s free weight counterpart.)

Machines Cons:

  • Repetitions with bad form will cause injury.
  • Stabilizer muscles aren’t called into action as with free weights.
  • Replicating the weight you lift with a machine won’t match up to it’s actual weight.

Recovering From Injury or Just Trying to Prevent It

Free weights are probably going to be the best method for building muscle. But if you train exclusively this way, you’re apt to feel the toll it can take on the body. Namely, the joints are affected the most.

That’s how machines can one-up free weight training. It won’t wear down you’re body as much. Using the bench press with a barbell for example, there’s shoulder strain that comes along with that exercise. Using a Hammer Strength machine in the gym will assist to reduce the amount of stress put on the joint.

If you’re recovering from injury then taking it slow and doing rehab on a machine is preferably the way to go.

The home fitness versions are easy to figure out. Targeting your back? Try the bent-over row as the free weight option. The classic chin-up is going to get you the same results as the lat pull-down machine. If you can’t do a chin-up, assisted or negatives will still get you the results as while build up your strength. There are plenty of other alternative you can pick to replace machine movements.

What I would like for everyone to take away of this article? You have options. No matter how you choose to lift, if you’re on one side of the free weights vs machines debate or not, making sure you’re performing each exercise with proper form and staying safe is the most important thing.

I vote for free weights since I don't belong to a gym. But sometimes it is a pain to switch the weights between exercises, I agree. Machines do have their place though. My 73-year-old father is recovering from hip replacement surgery (and has back issues), uses the machines only in his gym. He's had good results and honestly, it's just easier for him to sit on some of the machines to perform the exercises. I'm glad he's working out regularly so whatever works for you!

I think that machine are useful to learn a certain movement and master it. Then, you should progress to free weights as it does train the body harder.

I think it depends on the movement you're trying to master. Novices could warm-up with light weights to practice proper form. A dynamic warm-up is essential anyway, so this is one way to kill two birds with one stone. One group of muscles which no machine is necessary is the abs. I know there's a pretty successful industry for ab machines, yet there's plenty of exercises to help work those muscles like planks, reverse crunches, windshield wipers...etc...without you needing to shell out your hard-earned dollars. -Mitchell

Good post Mitchell. 1 thing that I personally find machines are good for is going to the next level. For example, when I go up a weight on chest press sometimes just getting the dumbbells off my chest is impossible. However, if I do a few weeks of heavy lifting on the chest press machine where I don't have to do the initial lift off my chest I can build the strength. After a few weeks this then enables me to lift these heavier dumbbells off my chest.

I do believe machines are a good way for beginners to learn how to do standard weight-training exercises. Most of the time the strength needed to complete all repetitions with proper form just isn't there. But after you've had time to bring your training inline with these needs switching between the two is a good idea, if you really want to start adding on muscle. -Mitchell

I guess it really decides what you define as a machine. A cable set up, to me, is not truly a machine. The problem with machines is that they don't train your body like it's meant to be utilized. Your body works as a unit and should be trained in that fashion (which can only be obtained with free weights - particularly barbells). For example, a leg extension machine works your quadriceps in isolation. However, in any real life movement, your quadriceps NEVER works in isolation. They always work in accordance with the hamstrings and other muscles of the posterior chain to balance out the forces that are being applied to it. So why would you train it in isolation then? This is the biggest problem with machines - they separate the muscle groups and thus train them in a way that is not biomechanically efficient. With this being said, I wouldn't say machines are safer. They train your body to work against your biomechanical means. If you want to truly be safe and build a strong, balanced body, stick with free weights - particularly barbells. Just my 2 cents.

Srdjan, You're right, barbells are a great piece of equipment. I think dumbbells have to be my favorite, however. I find they offer up more options when it comes to targeting multiple muscle groups, and at different angles. When I'm working the chest db's are my first choice. From incline presses to pec flyes--they always seem to deliver. Looking at most machines you'd find in a gym, they're typically based on isolation movements. That's just not how the body works in real life. Taking the cue from your leg extensions example, the quads are never a solo act. When you're training with machines the stabilizer muscles never get the proper attention they deserve. The strength one gets with training with machines when compared to the strength one get from training with free weights, in a side-by-side comparison, will never translate equally. It's those supporting muscles in the equation that make all the difference. The one benefit to machines that I like is they don't wear the body down a fast. So, those looking to prevent muscle imbalances, you know the dominate arm is always going to be a bit stronger than the other, I'd recommend unilateral machines. When I used to hit the gym, I tried to stick with machines that offered this function like incline chest presses, leg presses and lat pulldowns (just to name a few). -Mitchell

I guess we're on the same page when it comes to training. I like your points about the machines although I still only recommend them during rehabilitation processes. I just don't like the idea of training the body in a way that's contradictory to how the body is designed to move. That's all.
