As you already know Side Crow Posture (Parsva Bakasana) can be a test of patience. Sometimes cultivation of patience is the deeper reason certain asanas exist. Some Yoga students never quite get it, despite how many years they practice.
This could be compared to a golfer, who has never made a particular shot despite years of practice, games played, camps, lessons, professional guidance, etc.
Within the study of Yoga, asanas should be used as tools for self-mastery and not so much viewed as end-goals. The process of learning Yoga techniques happens on a multitude of planes. However, that is another matter.
Asanas that will help build upper body strength.
- Adho Mukha Vrksasana (Handstand Pose)
- Chaturangasana (Crocodile – Push up)
- Kakasana (Crow)
By using the Internet, we are learning and teaching Yoga online. It is not possible for me to see if your hips are a factor. You may want to discuss this with your local Yoga instructor. Below are a few very useful hip openers for your personal Yoga sessions
- Baddha Konasana (Bound Angle Pose) also known as cobbler
- Kapotasana (Pigeon Pose) also known as dove or swan
- Viparita Karani (Legs-Up-the-Wall Pose). When performing this pose you can widen your legs as your range of motion permits and this is easier to hold for a longer time.
Try to hold these asanas up to a minute at a time. This is a goal – in and of itself.
