It doesn't matter if you wear it only during exercise or running in the gym, but if you wear it as a daily routine, it may have a certain impact on the blood circulation of your legs, because it is tight after all, and then it is definitely not as effective as loose clothes in terms of ventilation, and it is easier to breed some bacteria. Anyway, it's ok to wear these pants when exercising, but it's awkward to wear them for a long time.
