GMB: Hypermobility Exercises: Keeping Yourself Injury-Free while Training

The article is appropriately clear that they're not qualified to give advice for people with EDS and other full-on connective tissue conditions, but it's got tips and some interesting exercises for building strength and stability at the point just before your end range of motion.

As always, I pass it on under Bruce Lee rules: take what works for you and discard the rest.

ETA: I'm not hypermobile myself so can't evaluate directly; if you are and this seems obviously off-base, please comment!
