Exercise Anywhere From The Comfort Of Your Chair

Exercise Tip 9: Isometrics

Isometrics, or isometric exercises, are a type of strength training in which the joint angle and muscle length do not change during contraction. The joint and muscle are either worked against an immovable force (overcoming isometric) or are held in a static position while opposed by resistance (yielding isometric). Isometrics are done in static positions, rather than being dynamic through a range of motion.

While isometrics can be performed almost anywhere at anytime, isometric training will only increase strength at the specific joint angles of the exercises performed. They also will not work your agility, coordination, flexibility, or anything else. Due to these limitations, it is good to perform other exercises in addition to isometrics. Isometrics can be performed with free weights or resistance bands, but the use of added equipment limits where you can exercise, as well as creates an added cost.
