What’s an easy cardio workout i can do at home?

Im 14 years old, 5’6, and i weigh 155 pounds. I want to lose 20 pounds in the next two months and i’ve been told numerous times that a good cardio workout everyday will make you lose weight fast. I want a quick and easy cardio workout that i can do at home (backyard is fine), and won’t take longer than 20 minutes a day. I DO NOT want to run, so please don’t throw that option at me.

I read that 15 minutes of jump rope a day is a good cardio workout, but is it adequate for me to lose 20 pounds in 2 months?

Any other reccomendations for a good cardio i can do at home in less than 20 minutes a day that will get me to lose 20lbs in 2 months?

Thank you.
