Why are repe­ti­tions not recorded again and again?
  1. Do you take a short break with the corre­sponding rest posi­tion of the barbell before each repe­ti­tion? This is neces­sary for older sensor gener­a­tions and after strong impacts. Pay atten­tion to the indi­cator in the training bar.
  2. Is the minimum distance to count a repe­ti­tion correctly selected in the settings?
  3. Are you connected to a Blue­tooth headset or similar during recording? Some models take so much band­width that Vmaxpro can no longer receive enough data to recog­nize your repe­ti­tions.
  4. Strong vibra­tions caused by loose iron plates on the barbell can prevent repe­ti­tions from being detected. We recom­mend the use of clamps.
Why do I not auto­mat­i­cally receive the Vmaxpro Trainer exten­sion as a customer of the first hour?

We assign this exten­sion auto­mat­i­cally based on certain para­me­ters. Due to certain circum­stances it can some­times happen that these are not fulfilled and then no license is granted. Just write us a mail and we will acti­vate the exten­sion for you manu­ally.

Why are very slow excen­tric move­ments not recorded?

Our measuring tech­nology, with its high demand on data accu­racy, has certain phys­ical limits within which it works reli­ably. Very slow eccen­tric move­ments in combi­na­tion with a fast concen­tric phase can lead to faulty record­ings.

Why doesn't the app give me any training recom­men­da­tions?

All recom­men­da­tions are based on the velocity profile for an athlete in an exer­cise. For this profile at least 3 loads over 40% 1RM must be recorded at maximum execu­tion velocity. Further­more, it is impor­tant for the accu­racy of the 1RM esti­ma­tion that the MVT is known. For this you can perform a set between 70 and 90% until shortly before the failure.

Why is my 1-RM wrong or jumps heavily?
  1. The 1-RM is calcu­lated from veloc­i­ties at different loads and the slowest execu­tion speed. This is assumed starting with 0.5 m/s and adapts itself by learning.
  2. Consciously slow repe­ti­tions with light weight lead to misjudg­ments.
  3. Were all weights entered correctly?
  4. Each vari­a­tion of an exer­cise, e.g. Squat or Front squat, must be created as a sepa­rate exer­cise in order to be able to make valid state­ments about the 1-RM.
How long does the battery last?

The battery of older gener­a­tion sensors normally lasts about 4 hours in training. This time can be lower due to external envi­ron­mental influ­ences, such as low temper­a­tures.

Not every discharge curve of the battery batches is absolutely iden­tical, whereby the app can partially display the charge state incor­rectly.

If very low battery life should occur perma­nently, please contact us and we will find a solu­tion together.

Our new sensor gener­a­tion has a signif­i­cantly improved battery life and should have no prob­lems.

Which exer­cises can be recorded?

There is no restric­tion on the type and number of exer­cises that can be created. The different exer­cise types are queried indi­vid­u­ally when they are created and can be config­ured accord­ingly.

For which devices and oper­ating systems is the app avail­able?

The app is currently only compat­ible for iOS devices with at least iOS 11 or newer. All iPhones, iPads and iPod touches that support this iOS are compat­ible. Right now we are looking for funding the devel­op­ment of an Android version.

Where's the Android version?

Even though we can’t provide an Android version at the moment, we defi­nitely plan to do so in the future. We do not have the neces­sary capac­i­ties for the imple­men­ta­tion. When the time comes, you will be informed via one of our commu­ni­ca­tion chan­nels. The Android version is defi­nitely the big goal for 2019!

What is the reli­a­bility of Vmaxpro's data?

In coop­er­a­tion with the Univer­sity of Magde­burg we have prepared various papers in which we have Vmaxpro compete against gold stan­dard soft­ware and hard­ware from VICON.
