Looking for a glute stretch for the inflexible

[BoarOnTheFloor]

Any recommendations?

Lay on your back with your feet next to your bum so your knees are up.
Lift one leg and cross it over your other knee.
Using the opposite arm pull the knee that is crossed towards the opposite shoulder gently

Have a look at these, various levels of stretching
This is level 1 so should be ok

Level 2-

Level 3 -

Thank you! I will try these.
