Squats and lunges
These two exercises have « jumped » versions, where you add a jump between two lunges or squats to add more cardio and make it harder. As for the other exercises, there are many ways to do them, depending mainly on your level. Squats and lunges may seem to work mainly on your legs, but you’ll have to keep your back straight and keep your abs strained for better results.
These exercises will help you build a little muscle while burning fat, but exercise alone is almost useless !
Remember to always have a balanced diet and be careful not to lack any nutrients, because that could be very bad for your health. Most importantly, always stretch before any exercise ! You can find stretching methods everywhere on the Internet, the best is to watch videos and do it at the same time. You should try to adapt the stretching to the parts of your body you’re going to work on. If you begin exercising, be very progressive so your body won’t suffer and you won’t feel discouraged. When you reach a higher level, you can add weights during those exercises ! I hope this can help you !
