I’m trying to bulk and I know you’re supposed to do high weight, low reps (e.g., 5x5s), but I think my situation is a bit unique. I find that when I’m at a weight that I can only do 5 of, I don’t feel it that much in the intended area, whereas if I lower the weight just a little, I can do about tripple the reps and I really feel it a lot.
For example, when I do dumbell bench presses at 35 pounds each, I can do 20+ reps and I really feel it in my chest and shoulders. However, if I go to 45 pounds, I reach complete fatigue after about 6 reps and don’t feel it in my chest or shoulders. My arms are just too tired to do any more reps. (Yeah, my weights are light; I’m a scrawny beginner.)
Obviously I’m lifting a much higher total volume at 35 pounds unless I do tons of sets at 45 pounds. Am I really better off doing the slightly higher weight and fewer reps? Has anyone else ever had such a big discrepancy in how much they can lift when they slightly change the weight? Thanks for any advice!
