I don't know your height. If you are over 1.7 meters tall, 125 can't lose weight because your weight is thinner than the standard weight.

If1.65m, generally1.2m is normal.

However, no matter how tall you are, if you want to lose weight, I suggest you skip rope or run, keep exercising for more than one and a half hours, eat more fruits and vegetables instead of fat, and eat some lean meat. After half a month, you can lose about 500 grams a day.
