I believe the correct answer is A. "Use full body movements to improve your health." This is actually the only option that even remotely mentions health - B has to do with looking good in a bikini, C and D promote power, not health. So, this only leaves us with A, because full body movements will have a positive effect both on your body, and more importantly, on your overall health.
The correct alternative is "Use full body movements to improve your health."
Fitness equipment requires the user to make full movement of the body, or parts of it, so that the equipment has a positive effect on the health of the user. So this is the only promise advertisers can make.
