Hi Vasanth,
Firstly CONGRATULATIONS for achieving a weight loss of 20 kgs. Your BMI ( body mass index) seems to be normal, but presence of love handles indicates that you may still have excess body fat percentage. I will suggest you to get rid of total body fat to get rid of love handles. Engaging yourself in heavy workout or pumping iron wont serve the purpose. Focus more on Cardio i.e aerobic exercises like walking, running, cycling, skipping etc. Studies have found swimming as the best workout for love handles as it is aerobic in nature as well as it works the lower/middle back, which is essential for balance and getting rid of love handles. Apart from cardio, do some toning exercises with special emphasis on oblique crunches and its variation. Also keep a track on your diet and lifestyle to make your efforts worth.
