Her guide is super tough and challenging. In her guide it also says that you need a certain fitness level to work with it. So how is it structured? On Mondays you train your legs, on Wednesday your arms and abs and on Friday you have to do a full body workout. Kayla also recommends to do 2-3 times a week endurance training in the form of LISS (Low Intensity Steady State – e.g. power walking) or HIIT (High Intensity Interval Training – e.g. 15 mins sprints). It sounds very time consuming and it is when you aren’t fit as I was, but now after 6 weeks I can usually complete the workouts in the allotted time. The workouts consist of two different circuits which you have to do twice and you have to repeat circuit as long as the 7 minutes are up. This means you start with the first circuit and repeat it as long as the 7 minutes are up. Then you take a short break and go over to circuit two. You repeat it until 7 minutes are up and then start again with circuit one. All in all you (should) need 28 minutes for every workout without warming up and stretching.
