This is a great idea and I was totally excited to get this. The only problem is that you only get the first 3 exercises free then you have to buy premium. That is upsetting because i was so excited for this. :(
this is brilliant! it's a great way for me to ensure that i am incorporating what i learned into my everyday life. i really recommend this!!
