Forget sit-ups — you only need a pair of dumbbells and 7 exercises to sculpt your abs
Build abs of steel with just seven moves and a set of dumbbells
One common misconception in the fitness world is that endless hours of sit-ups and planks must be done in order to build a strong and defined core. But who has time for that? Not us.
The good news is, you don't need an abundance of time to devote to training your midsection but building genuine strength and achieving definition in your core requires strategic exercises that will target key muscles. Online fitness trainer Britany Williams, has created a seven-exercise workout focusing specifically on the lower abs and obliques. Working on these muscles will help you achieve a balanced and sculpted core and all you need to complete Williams' workout is a chair and a pair of dumbbells.
It's important to note that no two bodies are the same and not everyone's abs are as visible as others no matter how many sit-ups or crunches you do a day. This can be down to various factors such as genetics and varying body fat percentages. Simply engaging in core workouts won't magically make abs appear. To enhance visibility, a combination of cardio and strength training is key. Additionally, for those carrying excess fat, reducing overall body fat percentage will also impact your results.
With that being said, the moves below will help in developing strength and definition and compliment any fitness routine. Read on to follow along...
What is the workout?
Prepare yourself for an intense session as you commit to completing 12 repetitions of each exercise, repeating the entire circuit four times over. This routine can easily be done at the gym or if you prefer a home workout, we recommend getting your hands on a pair of the best adjustable dumbbells.
This style of weight is ideal for home workouts like this core-based one as they allow for convenient weight adjustments, giving you the chance to start with lighter weights and gradually increase resistance for continued strength and muscle gains. You can read more on progressive overload here.
