Definitions:

Anaerobic

A type of exercise or activity that occurs in the absence of sufficient oxygen and relies on energy sources within the muscles, typically associated with short, intense bursts of effort.

Aerobic

Pertaining to activities or exercises that improve the efficiency of the body's cardiovascular system in absorbing and transporting oxygen.

Isometric

Exercise involving muscle contractions without movement, typically performed against an immovable object or force.

Isotonic

Relating to muscle contraction where the muscle shortens to move a load while maintaining constant tension.
