Has anyone run into this problem? I can't seem to get a pump on most bodyparts regardless of what I do. Back and calves are the only bodyparts I get a pump on. I've tried heavy weights and low reps, light weights and high reps, more rest or less rest in between sets. I eat plenty of carbs, therefore I am not depleted. I rest plenty during the day and at night. You name it, more than likely I've tried it. Is this an age related issue? (I'm a 50 yr old natty). The reason I ask if it's age-related is because this situation is fairly new. Pumps were never an issue until relatively recently.
