Diet and exercise are the two main ingredients in the weight loss equation. A combination of the two will help you shed the unwanted inches and pounds. I recommend focusing on how you feel and how your clothes fit rather than on the numbers (scale weight). Try hitting cardio before you eat breakfast in the morning to burn a little extra fat as well as later in the day.
Losing 50 pounds is not something that is going to happen overnight and you need to stay motivated and dedicated throughout the entire process. Stick to a good, healthy diet and five full days of exercise and you will see results in no time. So, try and do cardio twice a day (jog, walk, or bike) and hit the total body endurance training program below.
I recommend doing two sets of 30 repetitions of the following fitness routine. Good luck!!
