Isometric is a type of exercise that, unlike
traditional exercises, uses stationary movements as the basis for the workout.
This stationary position causes only the muscle to work out using resistance
and it's own endurance capacity. Isometric exercises are used for all major
muscle groups in the body and can be incorporated into other exercise routines
or can be a stand-alone regimen.
Isometrics is a form of exercise based on the principle of no joint movement or elongation of the muscle when exercising. What this means is that all exercises remain stationary and use a form of resistance in order to influence contraction in the muscle region. Isometric exercises can be used to target very specific regions within the body and work off of endurance and repetition.
Isometric exercises are numerous is range because they are simple stationary movements which cause the muscle to contract without exerting force. Isometric exercises can be done against walls, one the floor, or any surface that is a stable, resistance element against ones natural force. For legs, one can do basic squats that require holding the position and letting one's body weight cause the contraction of muscles
Isometric training works best with an understanding of muscle groups and what muscles are affected during specific exercises. This type of training can be a self-started initiative and can be molded around the needs of the person or the desire to target specific areas. Isometrics can be done at home, at work, or on the go; this provides flexibility and convenience for someone with a busy schedule.
