Aerobic exercise and proper diet
For more ab exercises: Anyone can be healthier, have more energy, sleep better, and feel better about themselves through bodybuilding. Also important is to minimize any tension in the neck, I do this by very lightly supporting my head with my hands or the weight plate The main reason to workout abs is because strong abs stabilize your lower back and shield you from injury but as a side benefit a 6-pack looks great. No whipping the head around or flapping your arms. Concentrate on trying to raise your upright exercise bike shoulders straight up towards the ceiling. Use slow movements and only use the abs. Form is very important in crunches, many people do them incorrectly and end up working out their neck or hips more than their abs. Aerobic exercise and proper diet are even more important than ab exercises in getting that sought after 6-pack. If you have the best abs in the world they will be completely invisible if you are overweight.
