Glad to see you decided to take action and are making great progress! You look good! If your schedule permits, there's no reason to stop at 20 min a day! Strength training is also very good for you. Adding another 20 min each day to do push-ups, squats, lift weights if you have access etc will not only make you healthier physically and mentally but really boost your confidence. Keep it up!
Thanks for your advice ... I will definitely increase my time....
