Ideal stretch repetition?

Hi fellas,

In terms of how many times to repeat a particular stretch in a session anyone know what’s most effective?

Cheers.

If u a beginner
Stretch for 30 sec in all 5 directions each
You can do it twice in the beginner stage.

Later one can increase it upto 20 mins
30 sec * 5 = 2.5 min = Round 1
In 20 mins = 8 rounds

I hope u got your answer
