itssquidstella I've had a rotten cold too
, hope you feel better soon (Adriene's Yoga when you're sick is good, as is her 10mins meditation).
I managed Day 23, Joyful, which was a good one to come back to, a few planks, but quite gentle and stretchy, loved the lying down hip rotations at the end.
I'm another one with tight hamstrings and a few years ago, I had tendonitis in my right hamstring. I also have a very tight left hip. I usually find I start a yoga session with knees slightly bent and often hips apart, particularly with forward bends, then gradually get to straight legs and feet together as I go on. The "runner's stretch" as Adriene calls it is also good, particularly if you do it dynamically, moving forward in and out of a low lunge.
