Hurting after workouts
Iphigenia is right you should increase your time gradually, so your body can adjust properly. Yoy might be sore from anywhere between 24 to 72 hrs, depending on how intense the workouts were. When I first started working out I would go all out, then I was really sore. Of course I learned it was best for me to take it slow and listen to my body, so I wouldn't get hurt. As for the soreness, you may be experiencing D.O.M.S. (delayed onset muscle soreness) because your body was not accustomed to the strenuous exercise. Treatment varies but usually low-intensity workouts help, along with a hot bath, and nice massage. If you can't get someone to give you a good massage use a foam roller (many physical therapists use them on patients relieve soreness, knots, and muscle pain). Check out ab-workouts-guide.com/foam-roller, you can find how to use the roller to relieve pain and muscle soreness. Above all else pace yourself. I know you're in a hurry to look good for the summer, but nobody wants you to hurt yourself. I hope you feel better soon. Good luck and God Bless!
I find stretching whenever your stiff really helps - not just once either but everytime you feel your muscles are sore/stiff. When I'm really sore/stiff I'll repeatedly stretch my muscles throughout the day. Takes the pain/stiffness away and I think it speeds up my recovery too!
Weights aren't good for your age. You'll stay short. Try more moderate workouts. Unless you are a crossfit guurl then its Ok to feel pain!
