Answer:
Get into a bikini by this summer with our muscle toner machine.
Step-by-step explanation:
All of the other answers have nothing to do with using fitness equipment, except the second and third ones. The question is what is something advertisers can promise if people use their fitness equipment? The first answer: "using full body movement." That doesn't even mention fitness equipment. The third answer: "power lift the heaviest weights in three complete workouts." This does include fitness equipment, weights, but it doesn't give a promise on why people should use their equipment. The fourth answer: "the juice only mixer will enable you to have more power." It does give you a reason to use their equipment, but it isn't fitness equipment. A juice mixer is a mixer for making juice liquid. That isn't fitness. Now, we go back to the correct answer: get into a bikini by this summer with our muscle toner machine." This does give a reason to use their equipment, and a muscle toner machine is fitness equipment. You just have to read the questions closely and cross off the wrong answers.
