Today’s exercise is a great way to continue building your column-core control. Build your best body by keeping the spine (Adam’s apple to tailbone) stable as you move the arms and legs. This is a challenging exercise because the spine is not moving as the arms and legs do the moving work. The column guided resistance band force really activates the abdominal wall. The abdominal activation keeps the back stable as I am working through the exercise motion in the video. Spine stability is essential whether you are doing a med ball sit-up throw or are rowing on a Concept 2 erg. Column-core spine control shifts the moving work out into the arms and legs. It is far better that your arms and legs to do all the moving work and keep your spine as a non-moving foundation. So whether you are training for Dekafit or are a rower or an obstacle course racer this is a great exercise.
