I like the 45/45 split workout. Mostly because I can leave the DVD in my laptop and do the aerobic one day and the muscle work the next.
But he's also got a 60/30 low-impact workout if that interests you. Really any of his aerobic workouts can be modified because he does the basic athletic routines and doesn't do the dancy stuff.
Gilad is one of the few male instructors I click with - he doesn't come across as having that macho faux-paramilitary attitude that a lot of them have. I don't know if that's because he was in the business when videos were still being geared mostly to women - the 45/45 video must be about 20 years old by now - but it's certainly been a training style that has worked for him for years.
I'm looking forward to getting the new ab workout but I'll wait for it to pop up on Amazon used so it's cheaper.
