Multi-joint exercises prevent you from lifting too much weight

Explanation:

Multi-joint exercises are exercises in which various joints (eg hip and knee) are moved. Generally beginners as well as advanced practitioners should begin their physical training with multi-joint workouts and then move on to more demanding workouts. This is because multi-joint exercises prevent you from lifting too much weight. For example, for a lower limb workout, we start with the squat or press which is a multi-joint exercise, and leave the flexor and extensor chairs for later.

fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges. the core principle of fluid balance is that the amount of water lost from the body must equal the amount of water taken in.
