Q: I once read in a book about one type of cardio exercise called 'the aerobic solution'In this cardio u do the following:
You start at stage 5(out of 10 overall)for 2 mins.Stage 5 is different for each person.For me it can be a brisk walking for other jogging or running.After u go in stage 6 for 1 min.After in stage 7,8,9 and u remain in each for one min.You repeat this process for 4 times but in the last try after 9 u go in stage 10 for one min.After this u go to stage 5 for one min so u can cooldown.Is this considered to be a hiit cardio?Is it effective as the classic hiit cardio?The book claims this is very good and should be performed 3 times a week only in different sessions between weight training.

A: It sounds like one of many variations on classic HIIT prescription (30-second alternating intervals of all-out running and walking. Or biking or whatever other form of cardio you do). It's easier than HIIT since 10 is obviously your maximum but you only hit it once and spend most of your time at relatively tame stages 5, 6, and 7. I am sure it will give you some results, but I see no reason why it would be superior to classic HIIT in any way (besides being easier to do).
