Very good programs!
The Instructions are very clear. Lucas has a very calm and friendly way of teaching. He always explains different variations, I found a fitting variation on every excercise. I had a lot of pain in my back and my hips so I bought the Happy Back Challange as well as the Hip Opening Challange (both take 21 days to finish). I started my days with the back challange & finished them with the hip challange. It became a routine and it helps me to enegize in the morning and also to calm down in the evening. After I finished the first 21 days my back got way better! My hips still hurt, but the range of motion increased significantly. I don't think I have to say that I startet my second go-thrue directly the day after I finished my first :) There would even be live classes included in the one time purchase. But I can't tell anything about them, since I haven't tried them so far. Over all I can absolutely recommend everything he offers. Also the price/value ratio is amazing!
