OK, I did it last night. Had to skip the guts portion b/c I got stuck at work & by the time I finished the leg workout it was 7:30 & after getting home just before 1 am the night before I was tired!
So, I am sorry to say this workout doesn't hold a candle to my gym routine. I did go heavier as Lynn suggested but even still I'm maybe a little stiff this morning, not seriously sore the way I am after the gym workout. I'll try to break down the goods, the bads, & the mixture of both:
The good stuff:
--it is a tough workout b/c it's not just resistance training, it also includes endurance & some cardio
--I definitely felt the burn in my quads (altho nothing today)
The bad stuff:
--it is WAY too long & repetitive. My gym routine is about 40 minutes--6 exercises, 3 sets 8-10 reps. I can't remember ever working one body part for more than an hour. I was getting really antsy & bored maybe halfway through.
--there wasn't enough serious ham & glute work for me. Like I said, I really felt it in my quads, but barely felt anything at all in my hams or glutes. Could be I wasn't using proper form, I don't know (I've been doing squats & lunges for almost 2 decades so I'm pretty sure that wasn't the case).
--no calves, but easily remedied on my own. However I do think a full leg routine should include some calf work.
The good & the bad:
--it seems to be more of a toning workout than a muscle building workout. I think it's probably a great routine for those looking to "shrink" lower body, but for ruler-shaped girls like myself who need to build a butt it's not the type of routine I need.
--cardio/endurance in a workout can be a good thing, depending on your goals. Personally I like to separate the two b/c I like to really focus on muscle building when I'm lifting. On the other hand, if you're not trying to build size but are trying to lose weight & tone, this workout is ideal.
I think the main difference between doing legs at home & doing them at the gym is the fact that gym equipment enables you to lift heavier. For example, I use the smith machine for squats & lunges. I can really load up the plates on it b/c I don't have to worry about lifting the bar up & over my head to rest on my shoulders--I just set the bar at the appropriate height before I put the weights on.
Gym equipment also enables you to really focus on specific muscles. I can hit compound muscles w/squats, lunges & presses, & then really concentrate on quads & hams w/extensions & curls.
I hope this doesn't come off as too negative--I do think it's a good product & will be useful when I don't have time to get to the gym. So while I can use it as a sub when needed, it definitely won't be a replacement. ;-)
