Hip pain after runs...from doing squats?

Believe it or not, I do not stretch before lifting.  This was advice given to me by my doctor and the power lifting instructor.  Most powerlifters and olympic lifters I have known do not (and I know a lot).  The theory behind that which has been supported and debated is that lifting should always be done in a comfortable range of motion.  So the warmup sets alone will get you loose enough.  Also tighter muscles are less likely to cause off plane movement much like a brace or weight lifting belt.   So what I do is a couple of very light warmup sets first than a super heavy set on my heavy days.  Than on the light days keep the rep range at 10 - 8.  I always stretch afterwards, but could do a better job of stretching between sets.  My routine is a little more advanced.  But the I believe the theory is sound based on my research and experience.  Once again I will mention I have only had one injury when that happened I always stretched pre workout.  But in your case I would recommend a light weight warmup set or to doing 10 - 12 reps.  Then add on the heavy weight.  Then if you want to finish with a burnout, that should be good to. 

I will state right now, I always streatch before runs, biking, swiming, and when I boxed.

Like I said the concept of pre-workout stretching is controversial.  Back when I stopped doing pre-workout stretches, it was an alien concept. In fact, now this concepts seems to be pretty mainstream based on my reviews of different materials I have linked here.  But remember, you still need to warm up.

I stopped getting in ring while in grad school.  But I continue to train.  In fact I was the local USA Boxing representative and a certified trainer and official, I just did not renew it.  I took a break this summer while training for my first triathlon and have continued this break until the end of October after my next one.  I'll start up again during the winter.  Believe me I tried to do lifting, boxing and Tri training, but that sounded to me like a quick recipe for burnout.

I might add that as far as being a trainer went, I specialized in assisting coaches with strength training their boxers.  Many coaches have the old school mentality that boxing and weights are not compatible.  I have proven time and time again that this is not the case.  However, it has to be tailored to a boxer.  That is how my current liftin routine evolved.  I have found power and olympic lifting are 100% compatible with boxing with minimal if any loss in speed.

I say keep an eye on the pain.  If it persists it may be a muscle imbalance.  Honestly most issues are.  More than likely the load you are now putting your problem area under is just too much with the addition of squatting.  I say problem area because the issue is normally one joint up or down from the pain. 

As far as stretching being controversial…. Well you have to really look at what kind of stretching you are talking about.  Dynamic stretching is fine.  This can be accomplished by a light jog or 10 minutes on the elliptical or just proper use of warm up sets prior to working sets on leg day in the gym.  Static stretching pre workout is a no no in my opinion.  I’ve read multiple texts that liken your muscles to rubber bands in the fact that they become more brittle and prone to tearing in a “stretched” state.

Are you using lifting straps for the deads?  They will fix the bar slipping and greatly reduce stress on the fingers. 

Haha.  My straps are somewhere in the bottom of my bag.  Lift raw or with chalk.  I really see no reason for the vast majority of triathelets to be lifting that heavy. 

Also Sharyn I think Glucosomine & Chondroitin (sp?) has a cumulative effect.  It will take roughly a month before you build up enough in your system to have a noticeable effect.  You may want to look at Cissus if you want immediate results.
