So I don't know what wrong with me but I really want that after workout ache.. You know that feeling in your muscles that makes you feel like you've done something. I don't really get that. I tried increasing the weight I use but still nothing I always get to the point where I just can't lift anymore but never get the ache even the next day I still feel great. Do I just need to push myself harder or am I doing something very wrong. Please help....
