hi mars,
I cannot answer your whole question, especially about the cardio burn part, but beginning Jan.1st, I started the lbs concept but I only work my legs 5 days, not 6. I do 3 days/wk with weights and 2 days of non-weighted floor work or non-weighted standing leg exercises and I am having really good results. It took about 4 weeks before I saw any visable outer results, I could feel strength gains in about 3 weeks, but to actually look at my thighs in the mirror and see some noticable change took 4-4 1/2 weeks (I was almost ready to give it up!) But it has changed the look of my upper thighs, my inner thighs are finally getting in control, and I've lost a "mushy" area at the top front of my thighs. It is extra work, but I am really liking the results, and besides the outer appearance changes, my legs are stronger.
I do cardio 5x/week as well, so my basic schedule is something like this:
mon: cardio/upper body weights/lower body w/weights
tue: cardio/upper body weights/non-weighted lower body
wed: cardio/lower body w/weights
thu: cardio/upper body weights
fri: cardio/non-weighted lower body
sat: total body workout (weights)
sun: yoga or stretch
The cardio varies between hi/lo, kickbox, and step and the length of the cardio depends on which strength video I'm doing.
But I am very happy with the results I'm getting, just don't expect instant changes if you do decide to do it, give yourself at least 8 weeks before giving up on it, I almost "threw in the towel" and just as I decided to give it another 4 weeks "just to see", my legs started responding wonderfully.
Let me know how it works for you in a few weeks if you decide to go for it
