Yoga For Beginners 30 Day Challenge Day 20. We're starting to practice a little longer and you may find the poses a bit more challenging. Today's focus is on twists and we'll work up to parivritta trikonasana or twisted triangle. We're also continuing the vinyasa style of hatha yoga. Please modify as you practice, and rest whenever you feel that you could use it. Remember, the pause button is always available for you!
