Redefine Fitness - Body Plus Smart Tights
1.1 What is myoelectricity
Fitness has gradually become a way of life. More and more people are starting to exercise. Braised in all the original fitness types in this site, there will always be value-friends who feel it is difficult to experience the feeling of muscle strength or do not know how to To determine whether the correct standard of action. For a long time, we have been concentrating muscles and the pumping sensation that comes with it as a criterion for the effectiveness of training. Is there a more accurate and objective method of judgment? Of course, some value-conscious friends who care about fitness may find that in some articles, when comparing the effects of different actions on muscle stimulation, a comparison chart of the level of myoelectricity is thrown out, which is the most convincing evidence that cannot be refuted. So what is electromyography?
In short, the nerve impulses are transmitted to the muscles to stimulate the muscles to produce electrical activity and contraction. The bioelectric signal that is guided by the electrodes through the electrodes and records the activity of the nerve-muscle system is the surface electromyography. The surface EMG signal is essentially the sum of the differences in the activity potentials of multiple motor units. Controlled by the central nervous system, it reflects the functional changes of the neuromuscular system.
All along, the commonly used EMG detection equipment mainly includes: Noraxon, the gold standard for the surface myoelectric market, with a single set price of 200,000 - 1 million;
Delsys: No need for pads, built-in three-axis accelerometer, single set priced at 150,000-500,000
Undoubtedly, even if the price factor is ignored, it is unrealistic to apply these devices in daily training. After the rise of wearable devices, athos combines surface EMG detection and compression garments.
1.2 Why not ATHOS
As mentioned above, after the rise of wearable devices, Ahtos combined EMG detection and compression garments to achieve more convenient detection of EMG signals during exercise. Although Ahtos has not been publicly sold in China, it has also been in contact with Ahtos. This product, from the perspective of a user, I will talk about why it is body plus not athos to redefine fitness.
First, the body plus increased the respiration rate, abdominal muscles, external oblique muscles, anterior tibialis, and gastrocnemius muscles compared to athos. The total number of pectoralis majoris, trapezius, latissimus dorsi, triceps, biceps, deltoids, external obliques, and rectus abdominis was set for my tops (pictured below). Muscle sensor.
Secondly, the sensor material of athos is conductive rubber. Excessive impedance affects the measurement accuracy, and it also causes a decrease in comfort. BodyPlus uses a flexible conductive fabric sensor that is the same material as the garment. I am prone to sweating. I sweat more in this weather in Guangzhou. At the end of training, there is no difference in the feeling of wearing a body plus and normal tights. Ahtos is not wet because I can't wear it, but in the dry state, the sensory feel of the two sensors is still quite different.
Finally, body plus provides a completely closed-loop system. Compared with athos, only real-time data can be monitored. The body plus can generate motion analysis reports based on the collected data after exercise, thus helping the bodybuilder to formulate corresponding plans after all. It is difficult to stare at real-time exercise data.
Since it is a singer, it does not say so much analysis, and it directly enters the topic.
Because it contains accessories such as chargers, clothes, core equipment, and pedestals, packaging is still quite large.
The first level is the manual, charger, data cable and base
The charging line is anker, quality is no problem, but if you can change to your own logo I think it would be better.
The charger is a product win, 5V, 1A, and iphone are common, but personally feel better. Like the data line, if it is mass-produced later, it can be replaced with its own logo.
Charging base. The work of the entire pedestal is exquisite, the card slot, the card head is precise, and there is a certain weight in the hand. It feels good. Especially the design of metal contacts has won my heart.
Metal contacts close-up
In particular, there is a bootup button on the bottom of the manual that specifically states that at the bottom of the market, the button should have been removed and it should be changed to an automatic bootup.
And core fit, skin material, moderate weight, feel in your hands can be a plate 
After turning on the power as follows.
The second layer of packaging is the introduction of core, tights, storage bag and body plus the whole closed loop system.
The core is the core processor of the entire body plus. It processes the human physiological signals collected in the garment during the movement, and then transmits the intuitive feedback of human detection data through the Bluetooth 4.0 transmission to the mobile app.
Three lights, lightning-shaped status lights, Bluetooth-shaped Bluetooth connection lights, and the other running lights.
Like the charging base, the design of the contacts personally feels very beautiful, and the number attached is the device number for Bluetooth search.

The following is the protagonist, tights, because of the built-in sensor, it can not be neatly tiled
In addition to the neckline has a non-slip belt, ventilation window is also designed under the armpit.
The front core base of the clothes is basically the same as the charging base.
The reverse figure of the tights can see the sensors set according to the muscle position.

Core fit, wearing a kind of iron man's sense of sight
With various data collected by core devices and clothing built-in sensors, how to use these data to guide fitness, improve plans, and strengthen training for weak points requires the use of the body plus APP.
3.1 Initial calibration
In the first use, calibration is required. Simply put, the maximum ability to measure muscles is determined by determining the maximum activation of the muscles through a certain amount of resistance training until exhaustion. If the target muscles are not exhausted as required during the calibration, then the corresponding muscle muscle level in the future training will be in a pop-up state at a time, losing the significance of monitoring. Another situation is that, with a certain amount of time training, the target muscle has a significant increase, then compared to the initial calibration data, it will be in a state of bursting, and this time it needs to be recalibrated.
On the APP's personal page, you can see the "Physical Fitness Test" item
Click on Fitness Test to see the following pages, Primary and Advanced Muscle Assessment, Cardiopulmonary Assessment, and Baseline Calibration. For those who have a certain fitness base, they can directly choose advanced muscle evaluation.
The muscle evaluation is mainly through some exercises to determine the maximum capacity of the muscles in this area. In contrast to the primary muscle evaluation, the advanced muscle assessment is performed by selecting each of the built-in pairs of sensors to select the exercise method for that part of the muscle, and the greatest possible effect is to reduce the influence of other muscles. Since I currently only received the tops, I only evaluated my upper body muscles.
3.2 Action Library
Also on the personal page, you can see the “Action Library†item. After clicking, you can find training methods for specific muscles. Users can choose according to three forms: exercise, exercise, play, use equipment.
Press "Sports" to select
Press "Exercise area" to choose
Press "Use equipment" to choose
In general, body plus provides a very comprehensive action template that basically covers the current mainstream sports.
3.3 Planning
How to arrange each training program is a question that I often asked in previous articles. In general, there are certain basic trainers who, after having a certain understanding of all training actions, will arrange training actions according to their actual conditions. For those who are new to fitness, watching a variety of training moves, they often look at the head and do not know what to do and what to do first.
For the two situations I mentioned above, body plus offers different solutions. For beginners, app has built-in training templates for different parts.
In the home page, you can find "Sports template"
Click into the "sports template", a total of seven categories, namely, fat, muscle, plastic, stretching health, home fitness, cardio training and running area
Each training can choose the corresponding plan in the "training plan", and the training plan can use the built-in template, or according to their own plan to add related actions to form a custom plan.
If you do not set a plan, you can click the "+" in the upper right corner to make a plan. This step selects the built-in template and you can exercise. If you choose a custom template, you need to continue to set your own plan template.
You can choose a single plan or plan for the week. Take the order plan as an example.
It is recommended that the name of the template be written to the part of this training for future convenience. There are several actions for the entire plan, and how many steps are set below.
Click "First Step" to select the action.
In the clicked page, the pectoral muscle training action is selected according to the exercise part "pectoralis major muscle". 
According to their own plans, preferences, choose a double arm arm flexion and extension. Click on the double arm flexion and click "Add custom template".
The action introduction page has a description of the action and an action point.
In the previous step, click "Add to custom template" to continue to select the number of times and number of groups in each group. Click "Finish" after confirmation.
Then you can see the plan you have just set in your custom template. After you have selected it, click on "Join Training". 
3.4 Action Analysis
Motion analysis can reflect the real-time EMG level corresponding to each action in the entire training.
Click “Action Analysis†and the following interface appears. The upper side of the screen reflects the degree of muscle activation, and the lower side records the entire movement completion action in the form of a video.
The following is a set of back exercises that I performed after completing the calibration when I was first used. I did not choose to pull down the straight bar and chose a hand-held device. It can be seen that even if the movement does not appear to be deformed, the right latissimus dorsi is significantly better than the left side in terms of the degree of muscle activation reflected by the electromyographic signal. The weight is 65kg.
Put a video
In addition to videos, there are more data-based sports reports.
As can be seen from the figure below, as in the video, my right latissimus dorsi and trapezius muscles are much more active than the left side, so I need to pay more attention to controlling the left side force, which is currently back to the left Add several sets of separate actions on the side.
advantage:
1. Monitor EMG signals in real time and intuitively reflect the degree of muscle activation. In training, it can be more intuitive to help find weaknesses in training and improve them.
2, APP for beginners and fans with a certain basis have taken care of, built-in templates and action library basically covers all training projects.
3, the use of fabric electrodes makes the comfort greatly improved.
4, easy to clean, do not have to worry about the impact of future monitoring use.
5, tights designed to fit the human muscle contours, compared to other tights, can help shape the shape of the muscles, more popular, that is, the muscles of the chest, shoulders, back, arm muscle lines show more perfect.
insufficient:
1. You can add a zipper on both sides of your clothes to make it easy to put on and off.
2, can continuously update rich action library, sports template.
The above is the evaluation of the body plus smart tights top, overall, this is a very my product. Maybe some people think it's expensive, but for me, compared to the expensive private lessons in the gym, the body plus can give you help is far from the private lessons. (Of course, if there is a championship-level private tutor, don't think otherwise).
The evaluation of the lower body tights will be updated as soon as it arrives.
There are any training questions. I am asked in the comments. I will reply one by one.
