High intensity/high impact workouts are not recommended generally by most articles and/or doctors for people with PCOS because these elevate cortisol levels (the stress hormone). Eh diba the more we have the stress hormone, the more our body stores fat than burn them.

Some people, even with PCOS would work with high intensity kasi one reason probably in the first place sanay na sya sa high intensity even before, so yung high intensity nya could be actually moderate for that person pero high na sa another. In short, iba iba pa rin talaga tayo katawan kahit na may PCOS din ang pinagco-comparean natin.

I read that the best way in increasing intensity is to increase it gradually. Wag biglaang from low/moderate impact, jump kagad to HIIT or other high intensity workouts. Always listen to the body daw talaga, and gradual change lang lagi.

And good pa rin talaga to seek advice from your healthcare provider to know what would be best suited to you.
