The ultimate core exercise... Were you need flexibility and strength to perform at your best!! If you've never done those they should be a part of your program... I used to think you get abs by doing sit-up and crunch but realize over time that the biggest contraction of your core musculature happen in a isometric matter where you resist flexion and undo hyper extension ... Aka keeping a neutral spine ☺️ #abs #lifting #weightliftingforabs #core #corestrength #resistingflexionandhyperextension #fintess #crossfit
