Software solution for simple 3D task?

I don't know if this is the right place, but it seems to be. I want to do one thing: be able to enter a person's physical dimensions... height, biceps, thighs, neck, etc.... (I don't mind if I have to take and enter in 200 different measurements) and then have the computer generate a computer rendering of the person ( clothes not needed, just underwear is fine ) so that I can motivate them in their weight loss and workout goals.

I don't need to learn about light shading, shadows, draping of fabric, backgrounds, etc. All I want is to be able to generate the body, and then give them a view from the side and front.

Is there a particular software that can do this easily with a minimum amount of learning? I tried googling, but came up with nothing good but that is probably because I had no idea what keywords to use. Any help is appreciated, thanks.

Try Poser

I didn't see anywhere in Poser to enter measurements. Am I missing something basic?
