This exercise is a great way to strengthen the core without placing undue stress on the lower back. Use the NRG BALL™ to assist on the chop coming toward the knees and use the NRG BALL™ to load the core as you descend onto the mat with the ball extended over head
Actively work the core by performing striking movements to the heavy bag. You can perform these movements standing or lying down 2-3 days per week. This type of training can add a new dimension to your regular ab routines and is able to be performed on any type of heavy bag.
This one legged plank exercise using the NRG BALL if very effective for strengthening the deep core muscles. The reason for the intense burning sensation during the exercise is due to the fact that the abs are constantly contracting to balance the body and maintain a stable position. The key to this exercise is to keep the handles off the ground, your hands should be directly under your shoulders, and make sure not to arch your back, and you will get the ab workout of your life.
This exercise is a variation from the regular crunch. I like using the NRG BALL & Stability ball because it challenges your core by having to balance as well as the added weight of the NRG BALL SYSTEM. In this video I show some I show some basic crunch movements that you can perform at the gym or in the privacy of your own home.
