What are some good ways to burn Calories

I dont Join a gym until soon, for the mean time Im at home, Im 5 foot 4 inches and weight 250. I cant do push ups because i get tired easily. I cant complete some excerise videos because i get tired easily and i cant complete it. I love Cardio expecially if its fun, I want to burn calories before i join a gym. what would you guys recommend?

Nobody can do much at the start. ...That's sorta the point. If we could all do tons without having worked up to that level we wouldn't need to exercise. You do the little you can and each day, each week, try to do just a little bit more.

That's how exercise works to produce beneficial effects. There's a technical term for it "Progressive Overload" which is a fancy way of saying that if you want to get fit you have to step out of your comfort zone a little and do stuff that's hard.

If you can do 3 push-ups at a time do that. Tomorrow to do 4. etc.

Let me tell you. Whn I first went to the gym, I used the elliptical. 5 minutes and I was covered in sweat. And now 3 years later, earlier today, I hit the 40 mile mark for the week.

Thanks for the advice guys. I need to build my stamina and endurance, Walking i dont get tired, Also a Cardio video I can last 15 mins at best, Dancing i love to do, I can last awhile with some low impact zumba.

15 minutes is 15 minutes more than 0 minutes. Do the 15 minutes.
Do the 15 minutes enough times, and soon you'll be able to do 20. And eventually 30+

When I started exercising, it was hard for me to even walk for 10 minutes. Now I can hike for miles.
