This pose right here is for my people with tight legs - you know, the ones who sit for long periods of time throughout the day, or who are on their feet all day, or the athletes, or the sedentary people - ok, let's revise. This is a pose that is beneficial for everyone.
Basically it's going to target any tension in the inner thighs and hips, which may alleviate low back pain and sciatica. So, yeah. It's a good one to have in your repertoire.
The biggest tip I can give for this pose is to focus on the exhales. For maximum benefit, stay in the pose for at least two minutes.
Two minutes?! You might be saying to yourself, "Self? That's a long ass time."
It is, but here's the thing. Anytime we want to increase flexibility and release tension, we need time to breathe, so focusing on your exhales for two straight minutes is going to be far more beneficial than holding the pose for three breaths and calling it a day.
Focus on letting your whole body be heavy, no effort involved, and let it soak up all the pose has to offer.
