Personal trainer and outdoor fitness expert Rob Jones shares five tips to achieve the toned stomach, reports femalefirst.co.uk.

* It’s not all about sit-ups: Sit-ups and ab crunches work your six-pack. But for better defined abs, spend the majority of your workout on exercises that burn more calories and shift body fat.

* Be consistent: Dedicate time every day to focus on your training and make abs an integral part of each and every workout.

* Hone your diet: You eat your way to a six pack, so watch what you munch and focus on foods and sports supplements high in protein that help muscle growth and keep body fat low.

* Vary your workouts: Vary your ab workouts daily to work the different muscles that run across that area of the body for the perfect balance.

* Core and more: Include both isometric exercises (holding exercises such as a plank or side plank) with dynamic exercises (where you contract the muscles such as an ab crunch) in every workout.
