Vital Flex Core ended up being head and shoulders above the other muscle stimulators we tried. It passed all our tests with flying colors, including the most important ones – delivering on all fronts with effectiveness, features, performance, ease of use, price, and available discount.

It can be used to target your abs, sculpt your legs, tone your arms, stimulate fat loss, relieve cramps, and improve your posture, all without the need to perform excessive, repetitive exercises.

As soon as we took the Vital Flex Core out of its box, it was clear that it was built using the highest quality materials. Its bright, high-quality LED display provides a clear and easy-to-read interface, and with its intuitive controls, we could access the information we needed quickly and efficiently.

Once it was on, we could feel the pulses working straight away, and after as little as a week, we started to see noticeable results. 

The EMS+ micro current stimulator pad is comfortable to wear, and there are 6 modes and 10 strength levels to choose from, so there really is something for everyone. The easy charge USB functionality is a great addition too. 

Although these kinds of features are usually only found on expensive models, the Vital Flex Core comes in at an incredibly impressive price point. There really is no comparable product when it comes to value for money.

Since it was launched earlier this year, Vital Flex Core’s popularity has skyrocketed, being used by everyone from high-level athletes to busy working moms. Now it’s trusted by thousands of people all over the world, helping them to achieve the bodies they’ve always wanted, without spending their lives in the gym.

The Verdict

If you want to achieve the body you’ve always dreamed of – without spending countless hours in the gym – then we believe the Vital Flex Core is the most powerful and cost-effective solution on the market.
