Dances are fun, fantastic exercises for muffin top removal;
you won't even know you're exercising!
Honestly, any dance will do, so you can take a dance based exercise class, do jazzercise or something similar in your living room, or even play dance based video games when you don't feel up to anything else.
You'll do even better if you work out with a dance that focuses on your hips and stomach.
Learn to tango or take up belly dancing, for example.
In addition to working off your muffin top, you'll also be learning something new!
