Floor-based ab routines consisting of the standard sit-ups, planks and crunches have had their day. There is no denying that these moves are included in the best core workouts for good reason, they offer a darn good ab blast, but it's good to spice things up with core training. To give you some inspiration, we've found a spicy dumbbell core workout that only takes 15 minutes to complete.
Working dumbbells into some of the exercises in this routine from trainer Britany Williams, will add resistance to your training, intensifying the demand on your core and making things a lot more versatile so you work multiple muscles and don't get bored halfway through.
