There follow some tips over what to avoid when training abdominal muscles:
1.Sit-ups: Don't do them! Although traditional "wisdom" has long stated that the sit-up is a good ab. exercise, this is not the case.

Sit-ups and other similar movements (which involve arching the back) involve the psoas muscles (which run from the front of the Legs, through the pelvic area, to the lower back), and these exercises are useless for abdominal development work.

2. 0ver-speedy expectation of results.
3. Lack of discipline: giving up too early.

Points 2 & 3 are also important as they play a vital part in ensuring exercise programme fail!
All too often, people start a diet and fitness programme and expect to be in shape within a week. When this fails to happen (as, of course, it will), their dedication decreases and inevitably the programme fails.

To avoid this scenario, keep your discipline. Work out realistically-targeted goals and work at them. Try not to miss even one session (the routines take more than 10 minutes to perform), because missing one session will make it easier to miss the next, and so on.
