Are you doing your core work optimally? 

Core work is very important, as it translates into everything we do, both inside and outside of the gym. But are you doing your core work optimally?

The plank is one of the best core exercises out there, yet it’s often done incorrectly. Take a look at the picture below. Which version of this pic are you?

Points of performance:
– neutral spine (do not look up or out)
– butt squeezed (this will keep your hips/pelvis from dropping)
