In training, isometric exercises provide a shock to the body that affects the skeletal muscles, central nervous system, and the cardiopulmonary system as it is not adapted to a static position and the muscles are not lengthened or shortened.RELATED: RECOMMENDED PLANS FOR YOU
You can incorporate isometric exercises into your training regimen in a variety of ways. In strength training, the exercise can either be utilized on its own, in circuit training, or in a burn out/finisher exercise at the end of your work out. Depending on the training program, isometric exercise on its own is a great way to improve core strengthening and stability. This muscle action is fantastic in circuit training since circuits involving super setting the same muscle groups, such as squats, leg curls and straight leg deadlifts, tax the central nervous system and the skeletal muscles. When performing lower body circuits, some great isometric exercises to add in are the chair pose, stationary lunge hold, and wall sit. Holding a push up at the bottom of the range of motion (elbows at 90 degrees) or holding a bicep curl at an elbow flexion of 90 degrees are a terrific way to incorporate into a upper body super set circuit. The isometric exercise as a finisher to conclude the workout will take you to the next level too.
While performing isometric exercises, it is imperative to maintain breathing and avoid holding your breath.These exercises increase internal body pressure due the skeletal muscles holding a prolonged contraction.
