Gym membership

Ok i finally joined a gym. Last Friday i went to LA Fitness and bought a membership, cause my friend Tia goes there and i need someone to work out with. So on Tuesday 28th, Tia and i went and worked out and again on 29th. She kicked my butt, i am so sore i can't walk and my arms, i can't straighten them all the way....OUCH! But i know it will get better!
