Optimum Nutrition is a bodybuilding equipment company that chose two different sales techniques in order to persuade people to buy pre-workout products. The company has followed different business techniques to spread its product and reach more customers. Their company launched two different advertisements, in which many athletes participate. The two different advertisements have the same idea, but with a different presentation. The company used celebrity, association, and repletion in the first ad, while the second ad highlighted testimonials, bandwagon, and association. These techniques are very effective and the company applied them in the hope of attracting customer attention to their product. The first ad was a short video showing the famous bodybuilder - his name is Steve Cook - how he used the product and how the product affects him. The first ad also incorporates the effect of him lifting weights while repeating words. Additionally, the first ad associates success with the product. In the first advertisement, the company tried to influence the customer by choosing the best guy in the industry to participate in their advertisement. The idea of ​​whether the builder buddy would use it means that all the buddies will use it. The second commercial shows different bodybuilders talking about the product and how the product helps them while they work out. The ad shows how the product gives the customer energy and focus while exercising. The second ad has a similar association as the first ad “associating the product with success and the trophy”. In addition, the company chooses regular and numerous participants to talk about it, to give people an idea of ​​how they are in the middle of paper......a day earlier by focusing and preparing . In addition, the first salespeople successfully highlight and tell the story of the product. The second ad also shows how bodybuilders managed to gain muscle and become successful. In my opinion, association is another powerful technique to convince and persuade people to buy a certain product. The two different advertisements were able to associate valuable targets for athletes with the product in order to make them have no chance unless they purchased the pre-workout. In conclusion, Optimum Nutrition is a very smart company and they used different persuasion techniques in order to cover a lot of customers. They used two different commercials and two videos that affect all athletes. They used the techniques of celebrity, testimonials, simple people, repletion and association to convince them..
