Two summers ago, as I was trying to get rid of anxiety and acne, I started a regimen of a 20 minute breathing/meditation practice and one ravi/ana DVD per day. I kept it up for over two months, and it was AMAZING. I also walked every day, as I did not have a car. When I would go to a hatha yoga class (1 per week or less), my SO always said I looked awesome.
My skin improved (which, unfortunately, revealed the scarring that caused me to have a complete mental breakdown, undoing all of the great things the yoga did
), my flexibility increased, my strength increased, my anxiety was lessoned, my focus was good, my breathing was soooo deep, and my sleep improved. I wasn't doing anything else during that time.
Unfortunately, medication has caused sinus irritation, so I can't do kundalini yoga and enjoy it (or breathing practices, which I think are phenomenal tools). However, I believe in yoga more than anything. I love other forms of exercise, but if I had to pick one thing to do forever, it would be yoga.
I guess, 5 years ago now, I spent an entire semester taking a yoga class. I did only that class (2 or 3 times per week), some sporadic cardio and some of Tracie Long's stuff. Honestly, I was in GREAT shape. I was getting compliments all of the time, and I remember very clearly, as somebody who has suffered digestive trouble her whole life, that my digestion was great during that time. Why don't I do more yoga????
