Final answer:
The REVERSE STABILITY BALL CRUNCH is an exercise meant to engage core muscles through lifting the hips and using the legs to roll a stability ball towards the hands.
Step-by-step explanation:
Performing a REVERSE STABILITY BALL CRUNCH requires coordination and core strength. While the information provided isn't directly related to the exercise itself, an accurate description for this exercise would involve lying face up on the ground with your hands on the floor for stability and your feet resting on the stability ball. The movement consists of lifting your hips off the ground and rolling the stability ball towards your hands, effectively crunching your abdomen in reverse by using your legs. This exercise challenges your balance and engages multiple muscle groups.
