Why do we fall out of the headstand?

The better the technique, the less strength we need to hold the body in the pose. The straighter the body is, the more correct the position. The abdominal muscles are tensed to provide stability. The breath remains calm. The eyes remain relaxed.

I can see from the picture that I am not completely straight. Any tilt must be compensated for with strength.

Even if the pose is perfect, I have the feeling that I won't be able to hold myself up at some point. This is due to the lack of strength in my arms and shoulders. This strength can be built up by holding the pose a little longer each time. I use a timer for this, which has an interval function. There is a small sound every minute. This morning I held Sirsasana for 2 minutes. I felt that this was my limit today. The goal is 5 minutes.

I am very motivated because I have signed up for an asana coaching workshop at the end of February. It lasts 2 hours. Participants should let the yoga teacher know in advance which asanas or sequences they would like to practise. I wrote that I would like to move from headstand to scorpion. Scorpio is an intense backbend and a challenging balance pose at the same time. I don't know what possessed me to write something so difficult. Now I'm trying to prepare myself. I practise holding the headstand a little longer every day. Over the next few days, I will also practise the backward movement against the wall. I want my body to be optimally prepared.

This asana coaching workshop is definitely my yoga highlight in February.
