The first 2 responses were ideal. Listen to what they said.
I would argue that you can do most of your exercise with your own body weight. Pullups, pushups, squats, lunges…these are the things that will work the majority of your muscles. If you want to challenge your body in a new way, consider doing a TRX suspension type workout. It's cheap as hell and you will work almost every muscle in your whole body doing 5-7 movements. That's the key to burning fat, using the larger muscles as much as possible until exhaustion occurs, and also making sure you contract all those little stabilizer muscles during the workout. Change it up for 2-3 weeks. Do your cardio at the end of your workout (you are in prime fat burning mode at that point), and make sure it's a high intensity interval cardio workout (basically go as fast as you can for 30-60 seconds and then a 2 minute rest in between). Here are links if you need more info.
