There is no way to target specific areas of fat. You just need to expend more energy than you consume and you’ll get skinnier. So do lots of exercise, decrease portions, eat healthier and sleep better. It sounds simple but it takes a long time and a lot of effort to build and maintain good habits.
I went up my Warning in NSW Australia, it’s about 1900m. I know it’s not that high but it’s hard to find people who want to go on long hikes.
