If you want to correct your spine, you can practice prone posture. The trainer lies on the yoga mat, with his feet together and straight, his hands hanging on his sides, his palms supported downwards on the ground, and then he lifts up and leans backwards with the strength of his palms and arms, with his thighs slightly off the ground and his abdomen kept tight, which will stimulate the back spine and make it correct. Long-term exercise is necessary.
