A client performs two repetitions of a bench press exercise with 130 lb and gradually decreases the resistance with each set unt
blagie [28]

Answer:

The correct answer is c. The client is using a Pyramid system.

Explanation:

The pyramidal method owes its name due to its structure: it is based on the gradual increase and decrease of the weight that we must ballast (if we require it in an exercise with ballast) or if we prefer it without additional weight, a gradual increase or decrease of the repetitions . All this increase and decrease in repetitions and / or weight, occurs in a staggered manner between each series for a single exercise, with the aim of being able to recruit a very high number of muscle fibers. It is usually done ascending or descending.

The descending pyramidal method consists of lowering the load, but increasing the repetitions, that is, it begins by applying large loads from the beginning and few repetitions, until ascending in the pyramid and completing the exercise having increased the repetitions and reducing the weight used. With this type, what we achieve is called the strength-resistance of the muscles.

Why do you think this is important for aquatic animals that live in very cold places?
Elenna [48]

Answer: here´s why

Explanation: Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. If water is heated, its volume gradually decreases.
