These. Are. Legit.

This is just another tool for you to add to your toolbox, with a slight variation from the HK Cable Chop. Take away one arm, now you’ve got yourself a new challenge. You’re stabilizing, mobilizing and strengthening. The holy grail.
This is going to fire up your lats, wake up your core, give you an excellent release of the hip flexors, give you motion in multiple planes and help you build up that resilient core. Try it out and let me know what you think!
