That depends on what effect you want to achieve. Yoga has many functions.

Judging from the short-term effect, you may only need a few minutes to see the effect.

For example, can I give an example? You straighten your legs forward first.

Try how far your hand can reach forward, and then reach back.

Hold for 30 seconds to 1 min. If you look at how far your hand can go, you will find that it is much more at once.

This is only a short-term effect. There is a certain scientific basis. When you relax your back muscles, your back will be less tense. At this time, the effect is more obvious than not relaxing monetary policy.

And if you are flexible, practicing Yin yoga will be very effective, and the effect will be obvious if you persist for one month.

Others, such as losing weight, may not be so obvious.

In fact, there are many reasons involved?

Like diet control?

Muscle changes from relaxation to tension and elasticity.

If you are really heavy, you may really see the effect in a short time.

But if you pursue the effect of temperament, you may have to practice for a while. The basic temperament of a yoga instructor is the result of long-term practice.
