a rotatable and pivotal exercise system for performing weight resistant training exercises comprising a support platform having a base and an integrated support structure for adding structural strength , integrity and stability to said support platform , a pair of pivotally attached resistance arms and a pivotal support device pivotally engaged with a pivot support base attached to said support platform for pivotally supporting an exerciser . the pivotal support device and system may be adapted to accommodate an exerciser performing weight resistant training in either sitting , standing or bench supported positions . an exerciser positioned atop said pivotal support device and shifting weight relative to the vertical axis of said adjustable pivotal support device will cause said adjustable pivotal support device to pivot and rotate , thus requiring the exerciser to use their stabilizing muscles to balance and stabilize themselves as the exerciser moves the pivotally attached resistance arms throughout an exercise movement .
