By now you understand that to work your core properly you must summon the strength of your entire body. But are you activating unnecessary muscles? In this session, focus on the overflow of energy. Overflow happens when you tense other muscles that don't need to be used for proper alignment and stability. Learn to use what is necessary and drop the tension from the rest. Begin in savasana for a body scan, before going into a full-out session. Props Needed: Two blocks.
