me too, I've done 4 days now and my knees are killing today. Just after I finished the 4th one I got a shooting pain down the side of my left knee and when I woke up this morning they were both killing down the back. I'm going to have a rest day just to be on the safe side. I had to take pain killers this morning so i could take my kids to school.

I'm hoping it just soreness and not an actual injury.

Advice appreciated from anyone.

Brilliant thank you, good to know it's 'normal'

Back to it tomorrow hopefully.

When I woke up this morning, my knees were aching. I did a 15 minute stretch routine and they feel a bit better now. (We'll see how my workout goes this evening though.) I've been trying to do extra stretching everyday since starting 30 day shred because I really don't think the video has enough.

My knees are sore too. I just took a few advil to see if that helps. I really want to do 30DS, but if it continues, I may have to take a day off.

Try to really, really stretch when you are done - even more than what is at the end of the video. I'm in physical therapy school now, and my only complaint about the dvd is that she doesn't stretch nearly as long as you should. You should hold each stretch for about a minute, or until you don't feel it stretching anymore. If you are feeling sore the next day, it's probably DOMS (Delayed Onset Muscle Soreness). NSAID's can help with that, and so can ice (no longer than 15 minutes at a time!)

Hope this helps!
