Isometric exercises are not about moving during the exercise, but about holding a contraction. The plank position is a perfect example of an isometric contraction: the muscles of the whole body work to stay firm and maintain a solid form. But there is another exercise that you should consider if you want to further improve the strength of the core muscles: the Holly Body or Holly position.
The Holly Body is an exercise that targets the lower back, obliques, and abdominal muscles, and strengthens the entire core, helping to improve posture, form, and running efficiency. The move requires no equipment (you can use a mat for more comfort), just a commitment to feel the burn.
Thanks to Ebenezer Samuel, Men’s Health USA Personal Trainer and Fitness Director, and Jess Movold, Runner’s World USA Certified Strength and Running Coach, we explain exactly how to execute the holly body and some of the best variations of this exercise for you. the abdomen that you can add to your training.
