Are free weights better than machines?
By Mert Yerekapan · Updated
Free weights are a little better for overall strength and coordination, but machines build muscle just as well. For most people the best answer is a mix of both, built around whichever movements you can do well and enjoy.
Where free weights win
Barbells and dumbbells make you balance and stabilize the weight yourself, which uses more small muscles and carries over to real-life movement. They also scale easily: you can load a barbell from an empty bar to hundreds of pounds, and they work anywhere, including a home gym.
Big compound lifts like squats, deadlifts and presses are mostly done with free weights for a reason.
Where machines win
- They're easier to learn, which is helpful for beginners
- They're safer to train hard, since you don't need a spotter
- They let you focus on the muscle instead of balancing
- They suit isolation work like leg curls, leg extensions and chest flies
- They're easier to use when you're tired or going near failure
Research comparing the two keeps landing in the same place: if you train hard and add load over time, muscle growth is similar.
A sensible mix
I'd build a workout around a couple of free weight or compound movements, then fill in with machines.
An example lower body day:
- Barbell or goblet squat, 3 sets
- Romanian deadlift, 3 sets
- Leg press, 2 sets
- Leg curl machine, 2 sets
If you're brand new, flip that. Start with machines for the first month to learn the movement patterns and build confidence, then add free weights. This is especially useful if gym anxiety is a factor.
Both count in League of Fitness. Lifting sessions come in from Apple Health and are scored by intensity and heart rate zones, so a machine circuit and a barbell day each contribute to your daily match.
Which one for fat loss or general fitness?
Neither is magic. Both count as strength training toward the two days a week that health guidelines recommend. Use what you'll do consistently.
If something hurts
A machine that doesn't fit your body can feel awkward or bother a joint. Adjust the seat, or swap to a different exercise. If pain is sharp or doesn't go away, see a doctor or physical therapist.
