Hmm, as a fitness instructor and instructor in several martial arts, I'd say that it seems rather too good to be true, really. Theories like this come and go - there are a few of these wonder routines invented every few years, and plenty per decade.
------------------------------
My take on things? If you do this program:
1) 15-30 minutes of
strenuous aerobics routines/martial arts on
alternate days of the week.
2) On the 'in-between' days, do thirty minutes of light running.
3) On two days of the week, replace the the aerobics/martial arts/running with a good weight workout - as heavy as you can go, and push yourself to keep increasing the weight or reps or both. Half an hour to one hour of this.
----On the weekends, go for a nice looong run, or better (if you can) hike in the mountains. Or if you want a break, do a light fitness routine like pushups, crunches, simple squats, etc. On some weekends push yourself - on others, do light routines.
If you have the time (and energy) to do all this, it will probably give you as good results as their 'system'. Understand that NOTHING comes easy in physical fitness - if you're willing to put your
sweat and will and heart and soul into a routine and keep it up for three months, then so long as your routine is even reasonably good, you're going to get massive results.
Time and Energy:
You see,
ANY competent instructor can give you a good fitness routine. The reason why many people are out of shape in today's world is
not because they don't WANT to be fit, of course they do. But they lack the time and the energy to do a strenuous routine after a hard day's work. And it's difficult to get around that.
If you can find the time and energy do the sort of exercise program I've outlined above, AND watch your diet, there's no reason you shouldn't get in shape in three months.
Heck, keep up
any strenuous program dedicatedly for THREE MONTHS and you're going to see results.
NOTES for people with knee problems: If you have knee problems, the running can be replaced by cycling and/or strenuous swimming (plenty of laps). And for those with bad knees, when doing weights, don't do squats (obviously), but by all means do heavy bench press and seated shoulder presses.
------------------------------
Now about breaking through a plateau, they ARE talking sense in one aspect:
What most bodybuilders do to break through a 'plateau' is take a break from the training - now, these people DO say this, but then they're only saying what
every dedicated bodybuilder
already knows.
However, I REALLY think that this sort of 'plateau breaking' rest period is more for bodybuilders and top athletes than for people just trying to lose a few pounds.
------------------------------
The main problem with keeping physically fit is not the need for a 'super-routine' but
how difficult it is for a hard-working person to SOMEHOW find the time and energy to exercise enough
BESIDES holding down a job and caring for a family.
See, I operate at peak fitness. But I'm sensible enough to know that that's not due to any 'greatness' on my part, but due to the fact that I'm a fitness instructor, and fitness IS my job. So I can spend half my day training - I do martial arts workouts, slab breaking feats, rock climbing, working out against a bag, weight lifting in excess of 300 pounds, yoga and tai-chi, swimming and heaven knows what else.
But this is not because I'm in any way better than anyone else, but only because I can AFFORD the time and energy to do it. If everyone could afford to do the same, I KNOW there would be a LOT of supremely fit people around.
