Summary
On episode 88 of 40+ Fitness, Coach Allan breaks down when to reach for free weights and when a machine is actually the smarter choice, using his own recent shift from strength training to a muscle-mass phase as the jumping off point.
He lays out three factors that should drive the decision: what you're training for, which of the three lifting modalities (strength, mass, or endurance) you're emphasizing, and what equipment is actually available in the gym that day.
The short answer, he says, is that it depends, and a good program uses both tools rather than treating one as automatically superior to the other.

Key Takeaways
- Free weights are more functional than machines. They move in every direction the way real life does, an awkward box, a squirming kid, an uneven load, so they train the stabilizing muscles a machine's fixed track removes from the equation.
- Machines generally offer more built-in safety. The weight stack sits beside or in front of you instead of over your head, and most machines have safety mechanisms that make it hard to drop a load on yourself, which matters if you're training without a spotter.
- Free weights are the better choice for building raw strength. Because they demand constant core and stabilizer engagement to keep the bar or dumbbell on track, they build the real-world strength a guided machine path can't fully replicate.
- Machines can be effective for building muscle mass. Isolating a specific muscle group without needing full-body stabilization lets you target growth directly, though Allan still recommends a base of free-weight strength work to support that mass.
- Machines suit endurance and circuit training well. They let you move quickly, adjust the weight in seconds, and flow from one station to the next, which is exactly what a muscular-endurance circuit needs.
- Equipment availability should drive your choice as much as your program does. If the squat rack is tied up, swapping to leg presses, a Smith machine, or leg curls keeps the session productive instead of losing the day entirely.
- Inspect machines before you use them. Frayed cables or anything that looks off should be reported to gym management, since machines can still cause injury despite their reputation for safety.
- Free weights and machines are largely interchangeable in a pinch. Most exercises can be done with either, so switching temporarily when your preferred equipment is busy won't set your program back.
