What is the difference between isometric core exercises and crunches? First off, isometric (iso meaning same, and metric meaning distance) exercises are those in which the joint angle or muscle length do not change during the movement, or, in other words, the body is held in a non-moving or stable position to help isolate the targeted muscle group. This type of movement is great for improving muscular strength and endurance without placing too much stress on the body.
Crunches are great for core strength and endurance, as well, and isolates the abdominals extremely well, but places unnecessary stress on the neck and back. For most, this is no big deal, and the body can handle the stress, but for some with injuries or general weakness, those movement can cause pain, and even injury.
Keep in mind that isometric core exercises are great for the body, but they, too, have a few disadvantages. Isometric exercises decrease the speed of muscle response due to the static contraction and do not require much blood flow compared to standard strength training. Increased blood flow allows for proper oxygen disbursement, which is required throughout the body.
These exercises tend to be rather boring, too, but make the most of them and incorporate them into your current routine whenever you can. Below is a list of the benefits of isometric core exercises as well as an isometric core exercise routine. Good luck and have fun!!
Benefits Of Isometric Core Exercises:
- Improves core strength and endurance
- Improves core balance and stability
- Less time consuming (constant muscle contraction is tough)
- Less stress on the body opposed to standard core strength training
Top Isometric Core Exercises:
(Try to preform a minute of each of the following exercises two or three times to isolate and target those core muscles)
