Crunch Time
I don't know if you're specifically looking to loose belly fat, but in general for pure fat loss, any sort of resistance training you can do is great. Cardio like running or biking is good for burning calories DURING the exercise, but it's not good at causing your body to burn more calories post-workout. It's a thing called "Excess post-exercise oxygen consumption" (EPOC). Basically, EPOC is about the amount of calories that your body burns in the X number of hours after your workout. Cardio will do a little bit but resistance training just about doubles it.
This isn't a great video but it's decent at explaining the concept.
Obviously you know your body and what you can/can't do, but if you can even do lower body and core resistance training you would do yourself a great favor in terms of burning calories and fat. Things like bodyweight squats, bodyweight lunges, calf raises, bicycle crunches, etc. will engage your muscles and cause more caloric burn than simply doing cardio. And if you can't do any sort of resistance, doing higher intensity cardio in intervals will also cause more overall caloric burn and provide better results.
There's a very popular trainer on Youtube named Mike Chang, aka "Sixpack Shortcuts" who has a training program based around the "Afterburn Effect" which is just EPOC. His program is basically common sense - healthy eating plus solid resistance training for the full body. Definitely not worth paying for (although you can find it on a certain bay of pirates).
