Is it permissible for Muslim women to practice Kegel exercises for their health benefits only?

Specialists who are trustworthy should be asked about the benefits of Kegel exercises. If their benefit is proven, then there is no harm in using them, provided two conditions are met: First, they must not be for sexual pleasure or gratification, as this falls under prohibited masturbation, according to the Almighty's saying: (And those who guard their private parts. Except from their wives or those their right hands possess, for indeed, they will not be blamed. But whoever seeks beyond that, then those are the transgressors.) Second, they must not require inserting anything into the private part, as this is a prohibited act and is not necessitated by any need.
