These are all forms of training that works with repetitions of muscle contractions. For example, during exercises that want to develop your strength in the biceps, you take a dumbbell in your hand (whatever the load), and starting with your arm “almost” outstretched (just your elbow a little unlocked), you go up the dumbbell up to your shoulder, and you release.
You have two methods for dynamic exercises: concentric and eccentric. The first involves speeding up the movement when lifting the dumbbell up, and the second is holding the weight when you release it. This is when the muscle is working the most.
