I did a class-length video for hip flexibility and then I found this awesome 17-minute long routine: Morning Wake-up/Evening Energy Boost. I loved it! It was definitely intermediate level, since she didn't take too long explaining the common poses (downward dog, warrior I, warrior II, and so on) and she included some new, harder poses I've never tried!
The instructor Tara goes really fast, so the 17 minutes fly by and your heart rate is up immediately. It definitely was an energy boost. Doing this video was the first time that I've tried the camel pose and it was hard! I can't wait to do this routine more and more so that part isn't so hard.
Enjoy! Let me know if you like it, too!
