Question

what is the main difference between free weights and a universal machine? (1 point) universal machines build bigger muscles because they allow for more repetitions. universal machines are safer because the weights are not above the body. universal machines are for advanced weight lifters only. there is no difference.

Explanation:

Universal machines are designed with fixed paths of motion and the weights are not suspended above the body like in some free - weight exercises (e.g., bench press with free weights where the bar is above the body). This lack of weights above the body in universal machines reduces the risk of the weight (or bar) falling on the user, making them safer in that aspect.
Building bigger muscles depends more on factors like progressive overload, proper form, and overall training volume rather than just the number of repetitions allowed by a machine. Universal machines are not only for advanced lifters as they can be used by beginners to learn proper form. And there are clear differences between free weights and universal machines.

Answer:

Universal machines are safer because the weights are not above the body.
