Here's the thing. If a muscle can't eat force, it will deform and cause other muscles to participate. This kind of training is a bad habit.

Suggestion: It's better to be light than fake. Remember this.

Through long-term group practice, the two weak hands have been trained to have equal strength on both sides.

Three target muscles, add a group to the weak side, and relax stretching.

I hope I can help you and adopt it.
