The key ingredient in training your core muscles for size and strength is the same as working any other muscle: resistance. This three-move workout does just that, hitting all the major fibres in your abs and obliques. Because you’re using extra weight, you need to speed up the exercise slightly but still keep the movement under control. So you should contract your abs into the exercise for a count of two, pause for one and then return for two (known as 212 tempo).

The more you can keep the muscle under tension during each set, the better your results will be so try to keep the pressure on between reps. After four weeks you’ll have bigger, stronger abs.
