Awesome! I´ve been recently reviewing the Hamstring lessons and when it comes to quickly reviewing, your PDF E-books are one of the most valuable resources! I can´t wait for the Ebook on the Lower Leg! I left a comment on one of the 3D models about a muscle I believe will be important to include that is not mentioned in the video lessons, by the way. Thank you and your team for all the hard work you people do to help us master Anatomy!
