Answer: The immune system.
Explanation:
The BOSU is a useful instrument for developing motor skills, kinesthetic awareness, proprioception, and static and dynamic balance. The core immediately activates and contracts when exercising on an unsteady surface to keep the body upright.
The BOSU forces people to simultaneously develop their power and balance through motor skills. Before using the BOSU ball, beginning exercisers should have good balance on the ground.These factors can be used singly or in combination to advance or regress an exercise or to change the exercise altogether.
These are the four factors:
- Movement
- eye contact
- external trigger (equipment, trainers touch, wall)
- Points of contact (toes, hands, feet, knees)
