Researchers acknowledge that the leg press is not an exact match for the barbell squat in terms of movement patterns, range of motion, and stability requirements, which is, of course, the point.
Machine exercises, whether it’s a Nautilus, Smith, or some other type, restrict range-of-motion, change the natural movement patterns of the body, and affect all outcomes of training including strength, hypertrophy, and metabolic effect.
Other reasons to avoid machines is that they place extra stress on the joints, lead to less power development (this has been shown comparing power output in a bench throw on the free weight bench and the Smith), less muscular activation, and less maximal strength.
Cable machines are the one exception that can be a staple for all trainees, whereas certain machines can be useful in rehabilitation or advanced isolation training, but free weights should be favored for strength, hypertrophy, functional performance, and fat loss.
