Take the time to build a stronger core and you can enjoy a plethora of health benefits, from improved balance and stability to increased endurance and a lower risk of injury. What's more, while you'll reap the rewards tenfold for your efforts, training your abs doesn't have to be a lengthy endeavour. 

Online fitness star and owner of the workout app Evolve You, Krissy Cela (opens in new tab), has crafted a core workout that will build strength in just eight minutes, making it a great option when you're tight on time. You won't need a fully-stocked home gym to try it either - all you require is a single set of dumbbells to make each exercise slightly more challenging. 

The best adjustable dumbbells (opens in new tab) are a brilliantly versatile tool for adding some resistance to your home workouts, but standard fixed-weight dumbbells will also do the job just fine for the purposes of this session. 

If you don't already own your own dumbbells, we recommend having a flick through our pick of the best Prime Day weights deals, with significant discounts applied to top products across Amazon. For example, right now you can grab a whole set of Brave Heart dumbbells for less than $160 (opens in new tab).

Hurry though, the exclusive sale event ends today (July 13th), so snap up a bargain while you still can.

If traditional core workouts tend to bore you, Cela's shorter alternative is an oven-ready solution. You'll be performing each exercise for no more than 40 seconds, followed by 20 seconds of rest before you move on to the next exercise. So, there's no time for your mind to wander. 

Plus, if you find one of the movements slightly too challenging, you can scale it back by lowering the weight you're using. This is where the BRAVE HEART dumbbell set (on offer right now (opens in new tab)) really comes into its own, with five sets of differently weighted dumbbells allowing you to personalize your workout. 

Below is a list of all the exercises you will need to complete the workout in full. It will take less than 10-minutes to finish two rounds so, unfortunately, time is no excuse.
