Whether or not Smith machines are an acceptable tool for doing squats is a subject of some controversy. The Smith machine has a couple of very useful safety features, such as height-adjustable stoppers that will support the bar if you get "stuck" at the bottom of the squat, and a self-spotting hook on the bar that you can rotate to lock the bar in place. While both weighted squats and back squats involve some sort of piece of equipment to add resistance, the two types of squats are actually a bit different.

Muscle spindles also are involved in motor control, providing constant monitoring and regulation of sensorimotor function, enabling appropriate body movement, both reflective and voluntary (Schmidt 1988, Gregor 1989). A few key variations to be aware of include: In this exercise, you hold the barbell across the fronts of your shoulders. [citation needed]. You, however, are a stranger in a strange land.
