Resistance exercises
Studies have shown that strength training actually increases the endurance of your muscles.

In fact, resistance exercises not only help to tune up an out of shape nervous system and increase the activation of motor units within your muscles, but also helps increase their overall endurance.

If you’re worried about overall size, remember: there are many types of strength training, and size and strength don’t always go hand in hand.

Answer

A resistance exercise is a movement that has an opposing force during the action. For example using weights adds a force that pushes against your movement. If you are squatting 100 lbs; the 100 lbs is the extra resistance that you have to overcome to complete one repetition.
