This is the resource I use for hip mobility and stretching out the hip flexors as I showed the group. In the picture he uses a foam roller to mobilise the hips but the group can use a golf club /instruction/2014/01/15/hip-mobility-and-lower-body-separation.html
This is similar to the SB Shoulder Mobility you and I have done (and I showed the group) except the club goes behind the head (not like in this pic).
I don’t have the time to put together a foam rolling video so this one here is quite extensive but covers off pretty much every aspect of the body! Although its targeted at women, foam rolling isn’t gender specific so this is good for everyone to take part https://www.youtube.com/watch?v=khC5J1lkC7s
