Step by step, run for 30 minutes every day, skip rope 15 minutes and swim for 20 minutes every day. If conditions don't allow, do the first two items, and change them to 40 minutes (until you stop running, you will sweat) and 40 minutes on the rope (your feet will jump alternately to avoid thickening your calves, but until you jump on the rope every day)! You can't lose more than 20 kilograms in two months. Come to me and I'll give you free personal education!
