This dumbbell ab exercise strengthens core muscle mass and burns fats in simply 25 minutes

Traditionally, if you want to develop your abs, the advice has always been to do endless crunches and sit-ups. These are practical exercises, but you can strengthen your core and build abs in a more varied way with this 25-minute strength workout.

While you could use the best abs to develop core strength, this short routine includes some top core strengthening exercises with dumbbell exercises designed to build lean muscle.

When you workout at home, all you need is a set of the best adjustable dumbbells. These adjustable weights combine multiple dumbbells into one to compactly build muscle without leaving home.

As useful as they are, the weights can be expensive. Dumbbells are on sale all year round, but today’s two deals mean you can save money on that muscle building machine right now too.

For those who work out in the gym, get a pair of dumbbells that will challenge you but aren’t so heavy that they affect your form. If you’re not sure where to start, check out these beginner strength training tips before you start.

Once you have weights by your side, you can adopt this abdominal-focused workout from fitness YouTubers Tiff x Dan (opens in new tab). The routine is arranged in trisets (groups of three exercises performed without rest), alternating between dumbbell and bodyweight sets.

Trisets are a great way to maximize the efficiency of your workout. Not only does this mean your muscles have to work harder before resting, but taking fewer breaks means you’ll get through the routine faster.

According to a study published in the International Journal of Exercise Science (opens in new tab), Triset training produces more noticeable muscle swelling than traditional resistance training. Researchers note that this increased swelling may also lead to increased muscle growth.

The Tiff x Dan routine combines this style of training with cardio-focused and weight-based exercises. The dumbbell moves help build strength, while the cardio activities aim to get your heart rate up.

Maintaining that elevated heart rate helps boost your metabolism — the amount of energy you burn at rest — resulting in all-day fat burning. This is useful if you want to lose weight or develop six pack abs.

You need to strengthen your muscles and reduce your body fat to achieve visible abs. You can’t target fat in specific areas, so you’ll need a fat-burning routine like Tiff x Dan’s or a HIIT fat-loss workout to see results.

If you’re looking for another way to build muscle and burn fat with weights, grab one of the best kettlebells and learn kettlebell swings. This compound exercise develops strength throughout, gets your heart rate up, and works your core.
