I can vouch for the 60 minutes of cardio...I do 20 minutes of cardio anywhere between 3-5 times a week depending on my schedule and, except for that rut I was in when I wasn't exercising, I'm averaging a weight loss of about 2-3 pounds per week. That's all I do. I have kids, I have a job, I have housework, I have, I have, I have....20 - 30 minutes a day is all I can offer cuz I don't want the rest of my life to suffer and that 20 - 30 minutes is working for me, so I'm gonna keep doing it.
As for the machines...wow....what an eye opener. So, what do we do then, for those muscle groups??? Just lunges and squats? That's what I've been doing for the last week and a half and man, can I feel those muscles days later!!!
