Before becoming pregnant I regularly attended a dynamic yoga class which was hard but very rewarding. Once I became pregnant I found noone would let me go to their class anymore! I desperately wanted to carry on my yoga, continuing with an adapted but similar workout intensity. Looking in the internet most of the prenatal yoga videos seemed to be focussing on stretching and relaxation, which was not what I wanted, so I was pleased to find this video, which is excellent! It has everything I wanted, the security of knowing you are doing no harm as you follow someone in the video appropriate to your trimester, yet a good workout and a feeling of really getting something out of it afterwards. Plus the all important relaxation! Fair enough it is less intense than my pre-pregnancy classes, but you need that as your body changes anyway. An excellent buy.
