If you’re seriously considering weight training and questioning whether to hit the weight machines or pick up those free weights, you've come to the right place, because it is absolutely crucial to weigh the pros and cons of the two approaches before you begin. 

Understanding the distinction between the two will help you pick the best option for you. And we're here to aid you with just that!

In a nutshell,
If you’re a beginner weight machines are the safest bet. They build you up by isolating and targeting individual muscle groups. For example, the seated arm extension machine effectively isolates and stimulates the triceps without straining the shoulders. 

But if you’re looking for a more versatile approach to weight training, free weights are the best option. They build you up by activating various muscle groups at the same time. Hence, they have a greater scope for building muscles than machines do.

A closer look at the safest bet,

Why say yes?

• ●    Machines are safer to use than free weights as the odds of dropping them on yourself while working out are very low. When they are used the right way, the possibility of getting injured is eliminated. 
• ●    They are made in such a way that it takes very little time to learn how to lift weights the correct way. They are an excellent choice for beginners, as they provide great support which makes them easier to adapt to.
• ●    Weight machines are the most reliable option when you’re injured or undergoing physical rehabilitation. They reduce strain on the injured parts of your body and ensure that you maintain good posture during the workout, which prevents further injury.

Why say no?

• ●    Holistic and well-rounded development of muscles cannot be achieved by solely relying on resistance machines. Machines might be great for building structure, but they don’t result in the complete development of stabilizer muscles and functional strength. This means that your overall performance and endurance won’t increase drastically despite you spending hours on the machine.
• ●    Lesser calories are burned as fewer muscles are worked on. So if weight loss is the goal, sticking to free weights will help yield better results.
• ●    For a full workout, multiple weight machines need to be acquired since they are specialized in nature. The cost involved, in purchasing and maintaining these machines is very high and they also take up more space than free weights.

A closer look at the versatile approach,

Why say yes?

• ●    A free weight workout can replicate the neurological pattern of fitness better than a machine workout. That is exactly why they can build muscles more efficiently.
• ●    They are the perfect choice when functional strength is the main goal as they can stimulate more muscles at a time.
• ●    When free weights, are used the right way they drastically, improve your posture and balance. As multiple muscles are worked on at the same time, muscle coordination also improves. 
• ●    They burn more calories compared to weight machines which means that you can lose weight faster by lifting free weights.
• ●    Free weights are inexpensive and more versatile than machines. A full workout can be accomplished with minimal weights as they are remarkably adaptable. They also won't burn a hole in your pocket in the name fitness.

Why say no?

• ●    The problem with free weights is that you can’t just pick them up and start working out since they aren’t exactly easy to use. You will need the right guidance and posture to work with these weights. Hence, they aren’t suitable for beginners.
• ●    Free weights come with a higher risk of injury. If the right technique is not used while lifting, you’re bound to hurt yourself. When working with heavier weights, you will need a spotter to ensure that you don’t drop the weights on yourself. This isn’t a problem with weight machines.
• ●    Since free weights aren’t specialized in nature, they won’t be able to isolate the specific areas you might want to work on to build up. Moreover, if you’re already fatigued or injured free weights aren’t safe to use, as they require greater control than weight machines do.

The bottom line is that both these approaches have their pros and cons. If you’ve never lifted before or if you’re recovering from an injury, weight machines are easily the right approach for you. But if you’re a pro at it already, you might want to branch out by using them in tandem. You can start with free weights and switch to the machines when you’re tired or towards the end of your workout. That way, you can achieve both structural and functional growth without overly stressing your body and risking injury.
