Whoever offers to another a bargain of any kind proposes to do this: give me that which I want, and you shall have this which you want, is the meaning of every such offer; and it is in this manner that we obtain from one another the far greater part of those good offices which we stand in need of.

— Adam Smith

While resting in between sets yesterday, my trainer nodded over toward the squat rack, where one guy was preparing to squat 675. “I’ll give you $100 if you go over there, step under the bar, walk it out, say ‘Light weight!’ loud enough for people to hear you, and then rack it.” I went over to the guy, explained the bargain, and offered to split the money with him 50/50 if he would vouch to my trainer that I fulfilled the terms. Work smarter, not harder.
