**Easy to Use:**
Experience effortless training with our smart shirt! Simple instructions include charging the controller hosts via the included USB cable, attaching them to the shirt's snaps, and spraying water on the inside fabric and electrode pads for maximum conductivity. For sensitive skin, a quick spritz on your skin is also recommended for optimal comfort.

Turn on your new fitness companion by holding the on/off button + for 2 seconds, and adjust the intensity and modes . With 39 intensity levels, you can customize your workouts to suit your preferences. After your 15 min. session, the device will automatically power off, but if you wish to end early, just hold the minus button until it stops.

**Important Reminders:**
- Always spray water on the golden booster pads and your skin prior to wearing the shirt for enhanced conductivity and comfort.
- While you can use it anytime, we recommend relaxing at home for the best toning results.
- For maximum efficiency, aim for five sessions a week, each lasting 15 minutes.
- Hand wash only with a mild detergent—never use a washing machine as it can damage the integrated wires.

Q: “What is GYM IN A BOX MicroCurrent Smart Apparel and why is it better than any Weight loss Drug "? 

Let's face it, weight loss drugs may promise weight loss, but they do nothing for your overall health and wellness. Sure, they may help you shed some pounds, but do they build muscles or improve your fitness? No. But fear not, because GYM IN A BOX is here to save the day.

Discover the Revolutionary Weight Loss Solution Backed by 60 Years of Scientific Innovation.

Achieve Total Body Toning with Patented ToneUp15®️ BodySculpting Technology!

If you are pregnant, not feeling well, have heart disease, MS, diabetes, cancer, epilepsy, a pacemaker or any major diseases, please consult your doctor first and do not use GYM IN A BOX..

Q: "Will it help me lose weight"?
ToneUp15® like mechanical exercises, makes your muscles work and thereby burns calories. Studies have shown that this can be a supporting factor in a balanced weight loss program.

Q: "Is it vibrating“?
The effect of the integrated ToneUp15 ® 
Massaging Boosters can make it feel like the product is vibrating, it gives you a tingling sensation while it contracts and relaxes your muscles. But this effect comes from the contractions of your own stomach muscles. So when you feel a vibrating effect, it is coming from your abs working out. 

Q: I used it frequently and I don’t feel the contractions as strongly as in the beginning anymore, is it defective?

A: No, that’s perfectly normal. Your brain got used to the technology and the flex and relax sensation going on. So after getting used to it by frequent stimulation, the contraction doesn’t feel as strong anymore, just like your first day at the gym versus weeks later, it doesn’t feel as hard anymore. 
However, please charge the power just frequently, or change batteries, depending the device .

Q: “I am thin, can I use it”?
Your body shape does not matter. Everyone can benefit from the effects of our ToneUp15® technology. Just because you are thin does not mean that your muscles are toned or strong. And even if they are,  can still help you to improve their strength and shape.

Q: “Will it create muscles and tone abs”?
Your body creates abs. But it does so only if it is stimulated to do so, that is why we exercise. Wearing GYM IN A BOX with active  ToneUp15® Technology is  great way to support this as it give you an easy way to achieve this stimulation without having to do taxing exercises on a regular basis. 

Q: "Can it hurt me“?
Any effective fitness equipment has the ability to hurt you if used incorrectly. However, working out with  ToneUp15® is particularly kind on your joints and back and can therefore be a safer option for working out than many mechanical exercises. If you follow the product instructions, the product will be safe. Always think of safety first whatever you do. 

Q: “Can I wash it"?
The Smart Apparel can be hand washed as per instructions, but the Power Host & the snaps must be protected from all liquids and moisture. 

Q: “ What does the technology do”?
The technology uses low level ToneUp15® technology to achieve muscle contractions that are similar to a mechanical workout, such as crunches etc. A the top level, it is used by athletes to achieve peak workout performance. For daily use it provides a great support for regular workouts without having to do taxing manual workouts. 

Q: “Will it make me slimmer”?
ToneUp15® like mechanical exercises, makes your muscles work and thereby burns calories. Studies have shown that this can be a supporting factor in a balanced weight loss program.

Q: “Is it safe”?
Any effective fitness equipment has the ability to hurt you if used incorrectly. However, working out with  ToneUp15® is particularly kind on your joints and back and can therefore be a safer option for working out than many mechanical exercises. If you follow the product instructions, the product will be safe. Alway think of safety first whatever you do.

Q: “How long to see results“?
Every body is different and there are no hard and fast rules. Depending on your body you may feel results from the very first use. As with normal workouts, regular use and a healthy lifestyle are preconditions for any positive results. Our research and testimonies vary from noticeable results within the first 8-10 sessions, 4-6 weeks, to longer periods. 

Q: “Can I use it at the gym“?
Yes. You can use GYM IN A BIX  in any situation that is safe, as it is wireless wearable FitTech. Adding it to your gym routine can be a very effective way in getting to your desired results sooner. 

Q: “How often can I use it”?
Exercise is only effective is it is done regularly. You can use GYM IN A BOX daily. Each program has an automatic shut-off to prevent over-use in single sessions. 

Q: “Which size should I choose”?
Please use the size instructions on the products website. 

Q: “Can men use it as well“?
Absolutely, GYM IN A BOX is unisex, gender neutral and can give men and women the same benefits. 

Q: “I’m 70 + can I use it“?
Absolutely, GYM IN A BOX can be used throughout all adult ages. However, if you have any underlying health conditions, please check with your doctor first.   

Q: “I’m pregnant can I use it“?
We do not recommend the use of ToneUp15® while you are pregnant. Please consult with your medical practitioner prior to any performance related physical workouts.

Q: "What’s the difference to conventional Shape-Wear"?

NO MORE BACK PAIN This technology is legit

I got this shirt by GYM IN A BOX a few weeks ago and already lost 2 inches off of my love handles and my BACK PAIN IS LITERALLY GONE! I assume it is from the contractions caused by the toning technology boosters, it is insane. Back is already much stronger and also works great on my biceps. Absolutely recommend this power shirt, I'll order the pants as well
