These are a very basic movement that will light you up if you haven’t done them in awhile. Make sure your body is in a straight line like there’s a wall in front and in back of you. Keep your pelvis neutral, no overly arched lower back power lifter or sprinter butts sticking out in the back. Now, just lower yourself under control, almost touch your bottom hip on the ground then squeeze your obliques to raise your body back up to neutral. You can also precede the reps with an iso hold.
