It is to learn, feel and contract muscles through stretching and training movements with different difficulties.

You can press the muscles in the training area with your fingers to help you feel muscle movement.

Definitely not massage, touching or buttock. It is impossible to passively activate muscles.

The subject's coach did have operational problems, or could not explain them clearly, without prior notice and permission.

It's not that your boyfriend is overly sensitive, and ignorant women are easy to get stuck in!

You'd better ask your coach to negotiate the training details. If you feel unprofessional, you'd better change someone else.
