Losing weight doesn’t mean you will have a perfectly shaped body. The important thing is to burn your fat mass. And to do that, you need to increase your bpm which means you need to run or swim or play basketball or something. Lifting weights do increase your bpm however, not so much. You are on a diet and if you have no problem with the schedule, consider buying a treadmill for your home instead of going to the gym every time. Perhaps, this will encourage you at home.
