Either after or the next day? I've been hitting the gym harder than ever before, and maybe its because of the stack, but I've noticed that I'm not really sore anymore. Do I need to somehow lift harder? I lift to technical failure on every muscle group, in my 5 day split, I work out fucking hard. However just a few hours after my workout, I don't feel anything, and I propably won't feel anything tomorrow. Do I need to tweek my routine or something? Thanks for the help.
