It is very common to have asymmetries in your hips.
If you find a symmetry muscle imbalance, you pick exercises to target the specific weaknesses or extensibility issues you're experiencing.
For example, if you have a weak butt muscle on one side, do extra training for that weak side. That could be glute bridges, bent knee hinges, single leg hip thrusts, etc.
If you have a stiffer set of hamstrings on one side, do extra hamstring stretching and lengthened strength work on that side. For example, you might do more standing hamstring stretches and slow controlled single leg hinges on the stiffer side to gain length AND strength.
If your glutes are much stiffer on one side, you might do extra glute stretching on that side. If your hip flexors are stiffer on one side, you might do more hip flexor stretching on that side.
In Practice
The simplest way to implement this strategy is to just do an extra set for the weaker/stiffer side.
So if you are doing two sets of a single leg glute bridge for both legs, just do an extra third set for the weaker side!
If you are doing one set of quad stretches, do a second set for the stiffer side.
