Sometimes I’m too lazy or forgetful to get things out of my yoga cabinet when I’m setting up for practice. So I am uncomfortable in some basic poses in a naggy way.
When I do remember, I’m inordinately pleased with how much better I feel in Virasana (hero) when I roll washcloths up behind my knees, and how much more comfortable I am in Adho Mukha Svanasana (downward facing dog) with my elbows strapped. It’s more than feeling better, though. Those props improve my alignment and stability, and help me get a greater benefit from the pose.
(My husband is a furniture builder. He made my yoga cabinet for sale several years ago. It didn’t sell, and I appropriated it for yoga props. I love it. He’ll never get it away from me now.)
