Other exercise ball exercises that reduce your point of contact with the floor to one unstable one are as follows:
Kneeling on the Exercise Ball
Standing on the Exercise Ball - not something I would recommend trying unless you have a spotter handy.
Hold this position for 5 seconds and repeat 5 times.
Hold this position for 10 seconds and repeat 5 times.
Hold this position for 10 seconds and repeat 10 times.
