On the ab rocket you should do the amount of sit ups you need to until you reach you reach your limit ( your stomach starts cramping/ hurting)
5 to 10 minutes. If you're really fat, you should do 10 minutes sit ups everyday.
crunches and sit ups
Jim Kelly's ab workout consists of a ton of exercises. For example, it consists of push ups, sit ups, pull ups, and bicycle crunches.
Many people think that sit-ups are the best ab exercises, but that is not always the case. For women, the Pilates beginner 100 exercise is very helpful for ab strengthening.
Crunches Sit-Ups Leg-Lifts
Speaking for experience, I would not purchase an ab lounger. You could save lots of money by doing sit ups your self.
If you want to tone your ab muscles, you will have to diet and exercise. Some of the exercises that you could do are sit ups, crunches, leg kicks and dancing.
Workouts that are good for building ab muscles are sit ups, crunches, and planking. Planking is actually an exercise that works the whole body.
Steadily increase the amount and sit-ups and do multiple sets, or you could try other ab exercises with a medicine ball.
No, a bike is not the best for abs. You should look into a AB machine at the gym or simple crunches and sit-ups.
The Ab Rocket is used to enhance an individuals abdominal muscles. As with any exercise regimen, a physician should be consulted prior to beginning to use the Ab Rocket.
Crunches and sit ups are the best. I hear Pilates is good too, and yoga. For more Ab workouts check out this site: http://exercise.about.com/od/abs/ss/abexercises.htm
