I am a senior three girl, with a height of 1 m 6 and a weight close to 100 kg, which should be considered as a small base ~ the goal is to reduce it to 90 kg first ~ and then stay here for two consecutive years.
I recommend going to the gym and setting aside two hours every day. Warm up for a few minutes in the first hour, then run on the treadmill for about 50 minutes (run for more than 30 minutes to burn fat), and stretch for a few minutes after running, otherwise there will be muscles in the calf. You can do some strength training after running, such as barbells, dumbbells, Smith squats and so on. If you really don't have the time or conditions, you can choose to do some aerobic exercise at home, such as jump it up2004, which has a good effect, but it lasts too long. You can do some stretching exercises after jumping.
Remember, it makes sense to practice three points and eat seven points. You didn't go on a diet, but you didn't check how many calories you ate. I suggest you download an APP for checking calories, so that you can determine how many calories you take in a day according to yourself and ensure the balance between calorie expenditure and intake.
I work in a gym, and I lost weight from 100 kg to 90 kg. I exercise less and it's not easy to rebound!
