All right, so Wednesday I did legs. Then Thursday I ran on the treadmill. About halfway through my workout my left knee started killing me. But, I was determined to finish my workout, so I pushed through the pain. I didn't notice any pain when I first got up on Friday, but after I did chest and triceps and started walking home suddenly my knee shot up in pain. I could barely walk without limping. It feels better now, but I'm hesitant to do cadio again tomorrow.

you know what to do....take it easy for a day or so...maybe do light cardio tommorow..see how it feels...STOP if it starts to hurt....as much as im sure you hate missing a workout, think about injuring it further and missing months of workouts....if pain persists see a doctor...i assume your making a transoformation for a healthy body...!!!...your joints and bones are as much a part of that as your body fat percentage...

:nono:

Often times I'll start out feeling creaky in the joints, but by a quarter through the workout I'm warmed up and the creaks are forgotten. When the opposite happens, I stop. Stretch lightly, take some ibuprofen... miss a day or two and get better. As xyouxfailmex pointed out, missing a day or two is a lot better than being out of commission for months.

By the way, glucosamine and chondroitin supplementation have really made a positive difference in my joint health. Especially my chronic shoulder issues.

Generally it's a bad idea to run through joint pain. I have experienced a good bit of it over the years and spent hours and hours researching it. The salient question is: Where did the knee hurt and how? Has it ever had a trauma? Did it swell up? Have you ever had, or have no instability issues with it? Were you running really quickly? Do you normally run at all? What shoes are you running in? Are you heavy?

The knee is a complex joint, responsible for handling vast amounts of force, often at bad angles, and knee pain can be caused by any number of things including loose or damaged ligaments, tendons, and cartilage. There are dozens of possible diagnoses for knee pain.

In the meantime, wait until it's rested up, do not run through pain, ice after a run if you do have pain (15-20 min), and gradually build into high-impact activities like running, if you've not done them in a while.

You may consider not mixing running and legs in the future. I found that the combination was too much and in fact I never work legs now, getting only cycling and running as my leg work (ergo, I never plan on breaking any strength records!). In my case, running can hurt my knees and squats can hurt them. I prefer running, so bye bye squats. If you're causing a bit of hardship on your knees with legs and then ice that cake of damage with running, it may not be surprising that it hurt. Cartilage damage, in my experience, will generally go away as time after the excercise increases. This isn't always the case, though, as some people with meniscus problems will get an aching a day after activity. I've had some pain in my MCL region after intense runs that only comes at about the 12 hour mark and is gone by 18. Knees are naughty and I would mostly recommend that when we're all able, we do total knee replacements with super-duper materials. Hopefully in a couple of decades they'll be more robust than they are now (the replacements, I mean).

Don't feel that you have to run. If you do some spinning you can easily get as good a workout as with running, if you're honest and put in a solid effort. It's easier on the knees because of the zero impact (they are still under duress, but not shocking duress like when you land your bodyweight on one leg).

Stop doing that. As far as joints go, "pain = no gain".

Time to switch over to pushups for cardio.

Running isnt necessarily the best cardio for knees in the first place. I would recommend mixing it up..bike, stair climber, elliptical. I tend to use the elliptical and then try to mix it up with stair master. If you are afriad of losing the intesity - try a spin class.

In regards to what is wrong with your knee..it might be tendinitis. Hopefully something that just temporarily flaired up.

So, how long should I wait before I start up cardio again? I haven't done cardio for about a week and a half now.

Hey you can do cardio right now. Just avoid the impact of running.

Do you a heart monitor? Have some dumbells available? Lots of fun available there for cardio. Have you got a step or plyo box? A bosu? Medicine ball? Weight vest?

Tell us what you have lying around and we can give you all sorts of low impact cardio that will be easy on your knee.

I don't have any of that stuff. I go to the rec center to do cardio. They have treadmills, elipticals, exercise bikes, and maybe some other machines. I'm not sure if they have medicine balls or step boxes...

Next time you are there ask if they have aerobic steps or plyo boxes.

But you don't have to go there to do it. Is there a staircase in your house? That will do. And even if you don't have one, that's OK, we just won't be doing step ups.

You have no weights I take it. Just one pair of dumbells around 15 pounds could do wonders.

Do you have an old knapsack that you don't mind getting beat up? Also you will want some plastic garbage bags and sand. Or bricks wrapped in rags. Anything that lets you put some weight in the knapsack so it won't shift around or poke you a lot.
