A large part of the exercises performed on these machines do not require the student to carry weights around the gym floor. To adjust the load, simply position the pin at the desired level. However, it is essential for the individual to learn to adjust the equipment according to their body measurements to ensure proper movement.
The likelihood of accidents during movements tends to be lower compared to those performed with free weights, since they don't require as much balance or body awareness from the student. However, this does not eliminate the importance of good professional guidance during training, as injuries can still occur on these machines, especially when the load is increased too quickly.
Beginner and elderly students - who typically have reduced joint mobility, low muscle strength, and poor motor coordination - often prefer machines due to the lower demand on complementary muscles to provide balance and stabilization to the body.
