Do Machines Build Muscle?

If you're aiming to increase your muscle mass, machine training can be beneficial to a certain extent. In this article, we'll discuss when and how to utilize machines for muscle gains.

Let's put an end to the ongoing debate: You can indeed build muscle using both machines and free weights. However, certain situations may favor one type of equipment over the other. To achieve optimal results, it's recommended to include both machines and free weights in your workout routine at appropriate times.

Before we delve into the pros and cons, it's important to note that machines have evolved significantly due to technological advancements. While barbells and dumbbells have remained relatively unchanged over the past 50 years, machines have become safer and more effective.

The Benefits of Machine Exercises

There are specific scenarios where machines can be advantageous:

1. Getting Familiar with Movement Patterns

For beginners, machine training helps in learning the correct movement patterns without the added challenge of balancing weights. Machine movements often follow predetermined paths, allowing beginners to rehearse and develop a feel for the movement. This foundation can later facilitate an easier transition to using barbells and dumbbells.

According to fitness experts, "Machines are a great starting point for beginners to learn proper biomechanics and develop a mind-muscle connection."

2. Maintaining Proper Body Alignment

Machines provide support and ensure proper body alignment during exercises. This is especially crucial for maintaining the correct posture and protecting the spine, from the neck to the lower back.

3. Training Without a Spotter

Machines offer a safer alternative for lifting heavy weights or training to muscle failure without a spotter. They eliminate the risk of getting stuck or injured, particularly during exercises like bench presses or overhead presses.

4. Easy Setup for the Lift

Machines usually have adjustable settings to accommodate different body types. Before starting your workout with heavy weights, it's important to test and adjust the settings to ensure a natural and comfortable movement pathway.

5. Reducing Joint Stress

Machine exercises can be less painful for individuals with joint soreness or those recovering from injuries. The restricted range of motion in machine movements reduces the strain on connective tissues, allowing for safer muscle training with less discomfort.

However, it's crucial to note that certain machine movements may exacerbate existing joint pain, so it's advisable to experiment with lighter weights before attempting heavy loads.

6. Isolating Target Muscles

While it's impossible to completely isolate a specific muscle, machines can minimize the contribution from stabilizer muscles and reduce joint stress. This emphasizes the target muscle, making machine exercises beneficial for experienced lifters. By using machines after heavy free-weight exercises, constant tension can be maintained, leading to better muscle isolation and fatigue.

7. Increasing Workout Intensity

Machines offer advantages over free weights when it comes to training beyond failure. Techniques like rest-pause, dropsets, heavy negatives, and forced reps are easier to execute on machines, as they eliminate the time-consuming aspect of setting up weights between segments.

When to Use Free Weights

While machines have their benefits, free weights have distinct advantages in certain areas:

1. Working through All Movement Planes

Free weights allow movements in multiple planes, engaging more muscles and promoting coordination. Exercises like overhead dumbbell presses or incline dumbbell presses involve pushing weights not only upward but also together, activating additional muscle groups and providing a wider range of motion. These compound movements are essential for size and strength gains.

2. Strengthening Connective Tissue

Free-weight training challenges not only the muscles but also the connective tissues, such as tendons and ligaments. The involvement of stabilizer muscles during free-weight exercises strengthens the connective tissue, which is crucial for overall stability and injury prevention.

3. Increasing Anabolic Hormone Output

Free-weight training places greater demand on the body, leading to an increased release of anabolic hormones like growth hormone (GH) and testosterone. These hormones play a vital role in muscle growth. By incorporating heavy compound movements, such as deadlifts and squats, into your free-weight routine, you can stimulate higher testosterone and GH release.

4. Accommodating Different Body Types

While machines can be adjusted, they may not always cater to specific body types. Free weights offer more versatility in accommodating individuals with unique proportions or limb lengths. It's important to find exercises that suit your body type and avoid positions that cause discomfort or compromise joint integrity.

5. Preparing for Sports and Other Activities

Free weights provide functional strength that translates well to sports and other physical activities outside the gym. Unlike machines, which restrict movement to a predetermined path, free-weight exercises improve coordination, balance, and the ability to adapt to unpredictable situations. Athletes, in particular, benefit from free-weight training to enhance speed, power, and agility.

6. Cost-Effective Equipment

If you're working out at home, investing in a simple setup with adjustable dumbbells and an adjustable bench can provide a comprehensive full-body workout. Machines can be expensive and occupy a significant amount of space, making them impractical for most home trainees.


Both machines and free weights have their place in a well-rounded training program. To maximize muscle gains, it's beneficial to start with free-weight exercises and finish with machine exercises as fatigue sets in. This approach combines the advantages of both equipment types while pushing your limits safely. Remember to customize your workout routine based on your goals, fitness level, and specific requirements.
