yea, you can base your rest periods based on a set heart rate(so when your heart rate returns to XXX you hit your next set because that means your body has returned to a determined base) but he says the majority of people find it a PITA or w.e. so though he explains how to setup your rest periods with HR the sample routines he has are based off of seconds.
The way these complexes work is combining cardio with resistance/weight training--so essentially you're getting 2 in 1 (similarly to p90x and insanity workout--but because you are your own gauge and because he takes out commercial fluff--it's not watered down)
He talks about studies where they had two groups of people: 1 did traditional exercise/workouts and the other did his method. The traditional worked out I think an hour a day, 3-4 times a week. The other group (B) for like 20 minutes or for same frequency of days.
Results?
Group A: burned more calories during the workout
Group B: resulted in higher VO2 capacities and just about every other gaugeable mark of performance fitness and health.
The issue with working on and empty stomach, is that though you will slim down, they've found that your body tends to metabolize your muscles at a faster level. It's odd, because on the other hand, in workouts you have degrees of activity before your body really registers conversion or metabolism of fat. For instance, IIRC the first level is burning off the immediate sugars and stuff like that, then it's pretty much adrenaline and hormones pretty much natures mechanism kicking in, but then you break into whatever stores you have left, and done right you burn fat.
The problem people have with high intensity workouts is Vo2 levels, pretty much if you're panting like a maniac than that means your body is starved for air; no air means no burning, which means decrease in fat burn and increase in metabolism of muscle. The issue is though, as your body gets acclimated to it, your body adapts and learns to efficiently take and burn oxygen (in other words your body's learning curve). The other biggest thing, is that the way Remedios compiles all these things, the workout itself is just a catalyst to what really goes on for the rest of the day, or the afterburn.
Essentially, his whole philosophy is on creating metabolic disturbance. So physics, an action will result in a reaction. SO if you cause a large enough metabolic disruption (compact and condense a full workout into a fraction of the time allotted) it's like when you draw the rock back on a sling shot. once you let that sucker go, the rock (proverbial metabolism) goes much further than the actual distance of pulling it back.
SO you may burn less calories during the workout, but guess who's metabolic furnace is supercharged? (I should mention however, that because of the afterburn effect, it would probably steer away from doing it about a day before a doctors visit, as people have found that their doctors have trouble understanding the afterburn effect and just take it as potential hypertension and things like that)
All in all, the book is 15 USD on amazon, and I found out i can get it electronically via kindle (or on my phone I can get a kindle app for free) and it's like an Hour read, I hardly see it as a risky investment lol.
