Whether you are seeking specific exercises to solely target your abs or you enjoy adding in a quick core burning set to a larger workout then this four-move ab challenge will come in handy.

If you have ever tried using an ab roller (we have a round-up on some of the best ab rollers) then you will know just how strong your core must be to use one effectively in a workout.

While ab workouts on their own won't get rid of belly fat or promise you a six-pack they will help to shape your abdominal muscles and build up a strong core. 

Home and gym fitness trainer known as @gainsbybrains (opens in new tab) on Instagram has shared the perfect no-equipment ab routine that will put your core strength to the test.

You can complete this at the gym or at home but just make sure you have a mat or something soft underneath you to protect your back as you perform the workout.

Sophie, who runs the brainsbygains page said in the caption to perform each exercise for 15 reps per side and do the routine twice over if you want to complete this ab challenge.

She also provides workout guides as part of a larger business side of brainsbygains but has gained her 2 million Instagram followers from her easy-to-follow and beginner-friendly workout videos that she shares online.

Fellow fitness star friends and fans of her workouts shared their respect for Sophie's ab challenge video in the comments. One user said, "Ab killer", while another commented, "Amazing abs ma'am, also insane challenge, definitely going to do this one".

However, if you are looking to lose weight and tone up your abs in the process this won't happen from only completing ab workouts. It is a good idea to mix up your training. 

Combining cardio with weighted resistance training as well as maintaining a healthy diet and ensuring you are consuming enough protein can help toward building a flatter and more toned tummy area. The best protein powder for women can help you up protein intake plus there are some brilliant Black Friday protein deals happening now.
