Ive just started lifting weights at home, i went easy on the lifting for the first 2 weeks, and 2 days ago i went really hard. i done 10x3 reps of 8 different lifting excerses, and my muscles feel really sore. Is this normal? should i just keep lifting and ignore the muscle sorness... ive been drinking plenty of protien... i just hope i dont feel like this after every work out.
