I want to know which part of the body jump roping works on if you just do the basic jump (up and down, no fancy jumping), and if jumping rope will really help a person lose fat.

Jumping rope will definitely help you lose weight. It is very effective. It is considered cardio, it gets your heart beating fast and burns a lot of calories. It uses your arms and legs for sure.
