If a muscle doesnt get sore the next day..does that mean that it wasn't work enough...I did a new bi's workout last night..Standing Curls and Seat Alt. Curls and my forearms are slightly sore and my bi's feel fatigued but thats it...What is the relationship between soreness and growth..My shoulder and legs grow the best for me and they usually are sore for at least 3 days...I'm just trying like me to grow..any help would be much appreciated..Thanx AGAIN!!
