Rest my ridulously sore muscles or keep pushing on?

Well, not really knowing anything about the 30DS program (frequency of workouts during a week), I'd say your body is telling you to rest. I lift/cardio 5x a week (40 mins weights/30-40 cardio each time) and if I do this too many days in a row with no rest days, my body just starts to break down and my workouts suck, and then I'm FORCED to rest to feel better. When this happens, I end up requiring sometimes 2 rest days in a row, which I don't like to do. I pushed myself horribly last week, and have decided to take off this whole week in hopes of recuperating from a sinus infection/PMS pains...

Listen to what your body is telling you. Soreness isn't necessarily bad - it simply means you're working muscles hard that you've not necessarily worked that way before. However, if you don't allow time for them to break down this muscle and build it back up stronger, you're going to wear your body down eventually.

Rest and do some light stretching.

I've read on the forums before that Jillian Michaels actually has said that the 30 day shred wasn't meant to be done for 30 straight days, and it is better to rest now and then to let the body recover. I'm not sure if that's true, but I have seen it from time to time. I'd say give yourself at least a day to see if you feel better.

I am always incredibly sore after the first day of the 30 Day Shred and I am in pretty decent shape! I would say that you should take one day off and then jump back in tomorrow. Your body will thank you and you aren't missing anything by taking one day off.

When very sore, I'm a fan of active cross recovery. Meaning I do something active, but gentle and while it uses the sore muscles it does so differently. Not a fan of using inactivity as recovery day.

Sore upper body from lifting - perhaps I'll do an easy swim.

Sore from running a race - often I'll take a walk with the wife and dogs.

Etc.

Since you walk a lot as a nurse, you may have that covered. Otherwise you could think about something else lighter intensity, but still active to do.

REST. A little soreness is good. Not being able to sit on the toilet is your body telling you to take a day or two off.

Google found this:

"You really need to do the program EVERY SINGLE DAY for results. It's very difficult in the beginning because you will be so sore, it will hurt to live. Jillian says work through the pain."

I have no personal advice to offer.

If you are feeling actual PAIN, then rest until you are healed.

If you are just sore, then working through the soreness will help ease the soreness. I know it sounds counter-intuitive, but keeping those muscles working (so the blood flow to those muscles increases) is the best remedy for soreness.

I've done 30DS and been in your shoes. I'd suggest doing a yoga workout today instead of a taking a day off. Yoga does a really nice job of stretching sore muscles and you'd be amazed at how much better you'll feel immediately! (Like being able to sit on a toilet instead of 'fall' onto it in pain, or walk down a flight of stairs without saying 'ouch' every step.) The yoga workout I have done on days like that is P90X Yoga, but I'm sure there are free yoga videos online. The P90X Yoga workout lasted 90 minutes, so I'd recommend finding one that is at least 45min to 1hour. Good luck!

I would rest a day, maybe walk and treat yourself to a nice long stretch afterwards, to help with your sore muscles. My favorite is a hot bath after, a little luxury after the hard work. Then get back at it. You are using those muscles in a new way, it's gonna hurt a little.
