Q8: How do I structure an ab routine?

According to the guidelines in Legendary Abs:

• Try to do sets in the 15-30 rep range.
• Follow the ordering rules in Question 7.
• Pick easy exercises to start with and when you can happily do about 2 sets in a row of an exercise, try harder ones.
• Only rest when you absolutely must, so take a short (10-15sec) rest between two sets of the same exercise, but none between lower and upper abs.
• Try to take about 1 second for each rep, except for ab crunches which you do slower (2 secs/rep) for a better contraction and 1/4 crunches which you should do fast (2 reps/sec) because you're hardly moving.
