Absolutely. Stick to it for a few months and you will see the effect. It will definitely be lighter. If you don't believe me, you will weigh yourself tomorrow. After three months, it will definitely be lighter. Running and skipping rope lose the most weight. It is recommended to jump rope 2000 times. 300 sit-ups are already intense, and it's easy to lose weight.
As for 200 push-ups, this one can't lose weight, and this one will gain muscle. If you just want to lose weight, you don't need to do push-ups if you want to practice your hands. 200 push-ups are also very strong.
