This core workout video from Team USA Runner Josh Cox. His pretty boy looks, body shaving and tattoos aside, he is a 2:13 marathoner so I personally won’t argue with the results.
I’ve personally been motivated by my back and hip-flexor issues to start doing these religiously. I’ve found that a desk job has killed my core strength and stability more than anything. This sort of activity should be an every day set of exercises. As this set of muscles is used to stabilize the trunk during distance efforts, it would behoove kayakers and cyclists alike to work this exercise into their workout regimen.
As I have the winter blues pretty bad and I want to go surfing something fierce I may as well focus on what I can work do right?
I’ve found the side plank and the threading the needle maneuver to be challenging for me and my real nemesis.
