Describe the effect that the speed of an exercise has on the posture and technique

Explanation:

The execution speed of the exercise is the time that lasts the eccentric and concentric phase of the movement. For both weight loss and hypertrophy, slower speed is more recommended in both phases of execution. The slower, the longer the muscle contracts, thus generating more micrioles in the muscle and spending more energy (ATPs) for the entire process.

In addition, slower speeds allow the individual to use a more accurate and correct technique, as well as allowing the individual's posture to be straight and aligned, avoiding spinal problems.
