When I was 20 I worked at a drug rehab facility. We had a crude "gym" there and one day I went in to do some benching with my patients. I told them my max was like 185 or something so they wanted me to make a new personal record so I had them load up 200#. I admit I wasn't very strong and still am not, but for them I got under the bar and went for it. When I lifted it, it felt very heavy but I knew that if I failed to complete the rep they all would likely get depressed and start using meth, coke and heroin again. So I gathered my strength and pushed like their lives depended on it, which they likely did! I completed the rep and and my patients went on to live clean and sober productive lives (I assume) thanks to me.
