I had got this to go with my aspiration to lose 100 lbs this year.
I did it 2 days the best I could and was like WOW this is crazy. I rested a day with just a 10 minute walk and got right back to it the next day. This week I alternated and did it Mon, Wed and Fri. On alternate days I did other cardio mostly its been Walk Away the Pounds but I want to start incorporating her Banish Fat Boost Metabolism in there on the opposite days. And I'm building in Bob Harper's Yoga for the Warrior some. I'd like to build that up to 2-3 days a week too. Its tough on arms that are already worked pretty well.
I have already gained precious endurance and stamina. Yes as she says she has 400 lb people that can do jumping jacks I got my 300 lb behind doing jumping jacks. I can do the first two rounds of them with little work which is a huge improvement from the first day when I seriously had to invent my own "modification" she won't speak of.
the jump rope is too hard on my knees so I skip rope and it keeps my heart rate up.
I'm stronger for sure. I have gone from barely able to push myself through 3 knee push ups to quite easily doing 10 in the last 2 weeks.
I've lost 4.4 lbs in 15 days so its not bad results so far.
