Final answer:
Pyramid training is a style performed in ascending or descending order, used in weight or resistance training to build strength and muscle endurance by varying intensity and volume.
Step-by-step explanation:
The training style that is performed in an ascending or descending order is known as a pyramid training style. This style is commonly used in weight training or resistance training programs. In an ascending pyramid, you would increase the weight and decrease the number of reps with each set. Conversely, in a descending pyramid, you would start with heavier weights and more intense sets, and then decrease the weight and increase the number of reps with each subsequent set.
For example, if you were performing bicep curls, you might start with 10 reps at 10 pounds, then move to 8 reps at 15 pounds, and finally 6 reps at 20 pounds in an ascending pyramid. In a descending pyramid, you might reverse that order.
This type of training is effective for building both strength and muscle endurance, as it challenges the muscles with varying levels of intensity and volume.
