How can I lose belly fat, thigh fat and arm fat from exercising but not involving an equipment?

Basically I have a lot of extra time and i want to lose all this fat i have on my amrs, thighs and belly but i dont want to diet crazy and i dont want to pay a lot. Anyone have good training ideas and tips? Somethng you can easily do at home without any type of equipment.

Ex: situps, pushups, etc.

Thanks (:
