I Swear every fit class does them
and I continue to see many people doing them wrong!
Here is a fun guide to learning about your body
and how to adapt towards this amazing full body workout
Remember to consult your doctor before you start this
or any other fitness program
When Planks are done correctly
the core should be shaking on each exhale
Most people find themselves holding their breath in this pose
I personally like to close my eyes during planks
this insures that I can feel each muscle in their correct place
and that I can fully focus on my breath!
