For safety, it’s best to first evaluate the functional fitness of the entire body, fingertips to toes. I always start core training in the safest manner. Start at the extremities of fingers/toes, and slowly travel to the elbow/shoulder, knee/hips, head/ spine and finally target the lower spine/abdomen. If you know tai chi then I believe teaching a few simple tai chi exercises is a reasonable place to start this examination. Next you put a little challenge into the tai chi exercise by adding a tai chi tool such as a CAQIT™ E-Z Pure Zip Energy Wake Up Exercise Bag. Once the trainee easily demonstrates adeptness with the CAQIT™ you can incorporate CAQIT™ PYTHON POWER Handgrip Strength Training. PYTHON POWER Handgrip Training delivers a significant challenge to the core structure. The next step is to go directly to the core with various planks of increasing difficulty.
