Since you said you have a total lack of exercise, I recommend you start a walking program first. I think this will give you much more benefits than the 10 minute trainer. I say this because, as you say, you are starting from square one. That means that ANY exercise you do, will give you benefits.
I think the walking program will be very good also because walking will help your body adapt to exercise and lead to less injuries. Since you are starting from scratch my fear is that the 10 minute trainer may cause some overuse injuries if you do it too much.
Because the 10 minute trainer is from the company Beach Body, keep in mind that if you try this program, they may try to get you to use their health shakes. You dont need these health shakes. there is nothing special about them other than that they are low in calories. I do. I have written extensive reviews on their products that I suggest you look over before you use them
