I am grossly out of shape, but am starting to get consistent with the 4-minute exercises. I am moving it up to twice daily. I feel winded during the workouts, and find it hard to maintain the form correctly, but am making strides in the right direction. I understand the importance of correct form and am striving for it. I feel better after doing the workouts…once I recover. Looking forward to the benefits as I am consistent! Thank you for your kindness creating a workout that even a grossly overweight, older person can do!
