You are probably not exercising property. You either have poor execution, use too much weight, use exercises that don't agree if your body mechanics or a combination of the three.

Feeling sore in the muscles is normal, feeling joint pain is not.

It's true you need more rest/sleep but I found you can work around it if you don't care too about putting on muscle and thus work out less frequently and with less intensity, just for the health benefits.
