I'm on day 6 now. I had to increase to medium after a couple of days as it felt a bit easy. The most surprising thing is the effect that it has had on my back. I have a lot of lower back problems but since starting with EA Active my back feels so much better. This has given me a very strong incentive to continue.
I've also just had my weigh in and was very surprised to have lost 2lb. Normally I lose less than that and I wasn't expecting to lose so much. Perhaps it's because I go to the gym once a week, though not every week, so I've already got a bit of fitness.
I've not suffered much with sore muscles, just a bit at the top of my thighs at the back. One thing I've noticed is that there are no stretching routines before and after the exercises. These help quite a bit at preventing sore muscles. When I used to go to step aerobics classes we always stretched at the beginning and end. I'm not stretching during my sessions now, but if I start suffering more with sore muscles, then I will.
I've just ordered My Fitness Coach as it's only £9.79 at Amazon. It will be interesting to see how it differs.
