I did Tae Kwan Do for many years, but I took a hiatus for a couple of years and now that I've started up again, I find myself ending nearly every class with a minor strain in my right hip. I started coming to classes early to do extra stretching, which has helped some, but I still seem to strain it on a fairly regular basis.
Are there some stretches, strength-building exercises, or other habits that will help me prevent this from happening/recover more quickly? Or modifications to common techniques that will make things easier on my hips until I'm back to baseline strength and flexibility? Related to this question, but I think more specific and I have been keeping that advice in mind.
