Squat Thrust
Start by standing, then send your hips back and down in a deep squat position with your chest raised, your hands on the floor between your legs, and the buttocks lower than your knees. Transfer the weight to your hands and then jump your feet back to reach the raised plank position. Quickly jump from toe to hand to return to a deep squat position with your chest up. Extend your legs to stand up. Keep repeating as soon as possible.
Dance it out
Dancing is one of the most fun forms of cardio you can do at home. Aside from being a great workout, it's also a good way to destress and produce some endorphins. All you have to do is blast your favorite song and let yourself feel the music. It will be so much fun that you won't even feel like you're working out. You can do it alone and dance it out while no one is watching or you can invite your friends to join in on the party! 
Zumba on Youtube
In the time of covid-19, gym sounds like a risky idea. Zumba works for me. I usually pick a “Zumba for beginners” video on YouTube and match their steps. It is fun, refreshing, and helps in toning my body.
Jump rope
While I'm more of a weight lifting kind of person, my mom loves doing cardio. After a few months though, she had grown tired of jogging on our treadmill. She bought a jump rope a few weeks ago and feel in love with it. Jumping rope is a great way to get your heart rate up and your sweat going. Try to build your stamina by going as long as possible. It may be hard at first, but you will definitely get it! 
Air Squat
Stand with your feet shoulder-width apart, your toes slightly out, and your hands crossed in front of your chest. Send your hips back down into a squat position. Straighten your legs to stand back on your feet, keeping your chest up and not rounding your back. repeat.
Use your stairs
If you've got a multi-level home, you can make great use of your stairs for your next workout! Running up and down the stairs is a great form of cardio. It gets your heart rate going and keeps it high for the entirety of the circuit. It's also a great way to include resistance through the incline. It will be much tougher than just taking a walk or going for a jog. 
Do a quick ab workout
Your abdominals are the easiest muscle group to workout at home. All you need is yourself! You can workout your midsection by doing circuits including mountain climbers, sit ups, and planks. Combine it all into a killer HIIT (high intensity interval training) session and you have got yourself a hot fire cardio workout! Repeat the exercises in rounds with timed breaks in between. You'll be sweating buckets in no time! Make sure you stay hydrated while exercising.
