A portable elastic resistance exercise apparatus comprising two panels selectively affixed in a 90 degree angle. Both panels are padded for user interaction. Elastic resistance is positioned as chosen within cutouts in the back panel, at any height and with any resistance chosen. Grips on the resistance enable either grasping or hooking around limbs or body parts. The apparatus folds for portability and also includes non-skid and other anchoring devices for temporary affixation to foreign objects and surfaces. The apparatus therefore offers a truly portable, all-in-one exercise device.
