I had two completely different people give me two different pieces of "advice" today while I was benching. I was feeling a bit off, and ask for a spot just in case. I usually don't use a spotter. Anyway, the guy I asked for help declined, saying: "If you are using a spotter, you are training too heavy." Another guy overheard and came over to spot, and he said "Don't listen to that guy. If you don't use a spotter, you aren't training heavy enough." Which is correct?
