The multitude of GYM IN A BOX 5 star Customer ratings speak for themselves!

Their expertise comes from being Fitness Technology Gym Owners and Experts for decades in Europe, but also they established the first Stim-Fit Gym in the USA in 2016, as Stim-Fit Pioneers in the USA.
Located between the exclusive Marina Del Rey and the fitness mecca of Venice Beach, the “E-Balance PowerGym” is frequented by Hollywood stars and starlets as well as the rich and famous of LA, allowing Nika and Nino to experiment with the latest fitness trends from around the world and constantly improving and perfecting ourselves to meet the fitness, beauty and slimming needs of some of the world‘s most demanding customers.

With COVID, of course, the CRISTIANIS fitness company was also closed for 18 months, so the couple decided to instead focus 100% on the development and production of the first product decoupling and successfully launched the first product during the lockdowns, helping people to stay fit at home and also enjoy the benefits of a nice massage. “ Look better, feel better & perform better with the push of a button only “ is the purpose of the new Power-Apparel Line.

This decision was the cornerstone for the launch of one of the hottest
newest fitness product: GYM
IN A BOX CoreWrap, Electronic Waist - Trainer/ Massager- Fitness Corset.

Nino Cristiani
has been a successful celebri-ty personal trainer and boxing coach for 30 years and has been a pioneer in the fitness techno- logy sector for 20 years. This extraordinary wealth of experi- ence flows into the development of theGymInABox™️product range on a daily basis. Nika and Nino, in particular, pioneered Stim- Fit Fitness Training in the US. It has the potential to revolutionize fitness and increase the effectiveness of conventional training by up to 20- fold.

In Europe, these cutting-edge training methods have been used at the upper end of the fitness spectrum for decades. For top athletes this means maximum training effectiveness and for everyone else a fit and toned body with mi- nimal expenditure of time. „Most people simply do not have the time and discipline to achieve their fit- ness goals. Stim- Fit Fitness technology can be the key to solving this problem, ”says Nika. To achieve this, Nika has developed the “Gym In A Box TM ” product line , simplified & miniaturized it and made in comfortable, safe and consumer friendly, delivering massager boosters that increase the sweat function , burn extra calories and tone the body while delivering a nice massage. ToneUp15 ®️ was born !

Approximately 1 million dollars in private assets and investments went into this development and GYM IN A BOX first product launch in the USA.

With the help of a team of fitness tech, fashion and startup experts in Los Angeles and Silicon Valley, Nika‘s goal was to adapt advanced fitness technology so that it could be seamlessly integrated into a range of exclusive but affordable athleisure products to be worn and activated in simple everyday situations. “Our concept ‘Gym In A Box ‘ will bring the revolutionary potential of Stim-Fit Technologies into our customers‘ everyday lives and enable them to look better, feel better and perform better in just 15 minutes a day” , says Nika.

Our GYm IN A BOX is designed for seamless integration into a wide range of fitness apparel. Designed in the glamorous metropolis of Los Angeles to be fashion-conscious and stylish, the first product GYM IN A BOX CoreWrap Electronic Waist Trainer“ was launched in 2021, upcoming products are the „Biceps & Triceps Sleeves“ and „Jeans Hot-Pants for lifting the Booty”, the Power-Yoga-Pants and a revolutionary new face mask for tightening the skin and jaw line .

Nika says with passion: “Achieving this was anything but easy. We had huge challenges due to COVID lockdowns, etc., the establishment of a new technology and brand in the USA, was associated with many hurdles and hard work and discipline. But I‘m so excited about what we‘re doing that it feels like nothing can stop us, never giving up, that‘s our motto. When people tell me, „You can‘t do that, you won’t succeed, it’s too hard “, that is my greatest incentive. In order to compete with Million Dollar of companies, you have to have courage and trust yourself and just work harder than anyone else. And this concept worked! Especially in these unprecedented times of COVID-19, we felt that we had to bring something to the world that would enable people to feel more beautiful, fitter and healthier from the safety of their own home, but also incorporate it into their conventional training routines to bring their fitness goals to the next level with GYM IN A BOX.

Usually these kind of technologies are only available to the rich and famous, and that‘s exactly what we wanted to change. We think, EVERYONE deserves to do something good for themselves and to feel better” , says Nika.

According to announcements released by Cristiani’s Balance, Fitness & Nutrition, LLC in Beverly Hills and Nika & Nino Cristiani, the CoreWrap is a posture enhancing waist trimmer that delivers the benefits of exercise without physical exertions.


This sweat belt, toning belt, and full belly fat reduction garment is cable-free, washable, and features invisible smart fabric integration for a shapewear effect and a very comfortable fit. The Smart Apparel is the result of years of R&D by Nika & Nino, and their efforts carried out at Silicon Valley and Silicon Beach have yielded this GYM IN A BOX™, which epitomizes advances in fitness technologies. In fact, this toning product for women heralds next-generation muscle toning technology for women.


The patent-pending ToneUp15™ uses Electro Muscle Stimulation (EMS) technology, and its Silver Muscle Contracting technology is present in all Smart Apparel offered through GYM IN A BOX™ to provide benefits that include muscle toning, abs tightening, fat reduction, and waist slimming. Pure silver ions woven into the fabric facilitate muscle contractions and initiate the coveted hourglass figure’s development. The Smart Apparel also helps mitigate muscle fatigue and soreness. The product is exceptionally stylish, luxurious, and very comfortable to wear; this makes it an ideal choice for evening walks, a stroll on the beach, or when stepping out to visit the supermarket.

The inventors have taken pains to ensure affordability without compromising on quality and effectiveness. Users will experience visible slimming results, fast. The apparel is easily controlled via the ToneUp15™ Controller; it allows the user to select any of the six toning modes and four intensities – muscle stimulation; performance boost, toning; shaping, anti-cellulite; massage, sweat, fat burn. The recommended optimum use for best results is two cycles a day or 12 minutes to 15 minutes each, which yields the effects of a 2-hour regular workout.

Gym In A Box at the STAR TRIBUNE

The GYM IN A BOX™ is a new take on a successful existing technology that has been used successfully in Europe. It is revolutionary, and it is for women. The company is proud to play a role in enabling women to gain fitness, health, beauty, and feel better in these uncertain times when lockdowns and social distancing norms have ushered in a new normal where maintaining a fitness schedule is no longer easy.
