I was referring more to training with heavy weights and exercises that directly put pressure on the problematic area. Would be pointless to use all these supps and then not even being able to to light weight exercises such as cardio, and I assume dancing might be similar (depening on what exactly, more stressing, but I would guess still way less stressing then with heavy weights directly on your problem area). Actually Cardio / dancing will be of benefit for your joints once the inflammation is gone and all nutrients your joints for regeneration need are in place, because this will speed up metabolism of the cartilage big time.
I can only only say that before my supp combo when I did cardio, I felt the inflammation afterwards, now its gone. So I would say chances are good for you.
As a guideline, what made me 99%(good enough for me) whole again:
curcumin (longvida 500mx 2x/day, can go up to 2000mg/day but quite expensive, I would add it if the other stuff does not get inflammation under control after a while, or use a lower quality product)
celadrin 500mg 2x/day (can go up to 3x/day)
cissus 800mg 3x/day (but a 2 week loading phase with twice the dosage)
glucosamine 1500mg (maximum dosage)
chondroitin just what was in my glucosamine supp, I would guess 200mg or so, but optimum would be 1200mg/day
acetylcysteine 500mg/3x/day together with 500mg vit c and 500mg sodium bicarbonate (taking it bulk, to remove the acidity, tastes better too)
o3's about 600mg/day, but that is way too low to have an effect on joints I think, if you want to try it for your joints you have to get higher, it might actually work really well together with celadrine
MSM... a lot of it actually, but that was due to other supplements that made me need more sulfur, so I guess 1-2g might be enough, keep in might that your digestive tract has to adapt first, otherwise you'll maybe get the runs so start low.
vitamin D 10000iu from monday to friday, weekend off.
I think thats it. the most expensive is longvida curcumin, and high doses of o3's, maybe cissus, the rest is fairly cheap.
As a side effect you will have a great prevention of cancer and cardiovascular disease, etc...

It's all healthy stuff that affects your whole body in a good way so you invest not only in your joints, but in your overall health. Was a no-brainer for me.
