Christy, did you enjoy the class hun? If so, I reckon you should keep going . Be warned if you 'go hard' with a weights session you'll feel sore just as you are now. You're body is recalling all these muscles it knew it had - but weren't really using to their maximum potential. You're now just waking your body up and this is a totally natural and normal thing to occur.

I find that 48 hours after a 'new' or 'harder' training session is usually the worst! And you've done the right thing my continuing on with light treadmill exercise to keep the body from stiffening up even worse. The more you keep those muscles moving the quicker they will become your friend once again .
