If you are a beginner in yoga, it is recommended to start with a simple stretching action.

Yoga pays attention to physical and mental balance, and many postures require strong stretching ability.

For example, many bodybuilders will choose yoga to improve the muscle curve and streamline it after exercising enough muscle blocks.

For example, the simplest way to tighten your knees is to touch your toes with your fingers and stick to it. The leg muscle lines will become very beautiful and your legs will look very slender.

There are many tutorials online, so choose one that suits you and stick to it.

I hope this helps.
