Not the normal ouch either. My joints hurt!

A friend & I started walking & pilates 2 weeks ago. Most of the pilates has been floor stuff, but 2 days ago we did a 20 minute fat blasting work out. Alot of jumping around baisically.

Anyway, I was expecting my muscles to hurt, they are pretty good now, but my joints! Ow! My knuckles, wrists, hips & ankles all ache bad. My lower back is killing me too.

Why? My hips & ankles fair enough...even my back I kinda understand, it can't take much, but my fingers & wrists? There's not much they really need to get used to? No spirit fingers!

Could it just be as simple as not enough water or something? OMG even my toes ache!

Is this normal? I'm getting up & walking around like an 80 year old man!
