Core exercises target the same muscles that crunches do — but they also include your hip and lower-back muscles. So what's a true core exercise? One that trains you to keep your spine stable and in its natural alignment.

Calorie Counting — I count my calories to make sure I’m on track everyday. I highly recommend the HealthifyMe app. They have an excellent database of food and dishes that you can select and track calories for. They also provide the exact macro breakdown for foods with a day-wise and week-wise analysis of your nutrition. I averaged out between 1500–1600 calories on Cardio Days and 1800–1900 calories on Weight Training Days.
