The advancements in the (micro) technology and analytics achieved that their accessibility and affordability to the average gym goer increased tremendously in the last couple of years. Everything started with live HR measurements, and eventually resulted in the GPS watches and activity trackers, as well as barbell/body velocity trackers such as the PUSH device.
Focusing on the velocity trackers, the big question is what can one expect in the years (or maybe months) to come? In short, my opinion would be, besides improving precision and cost, the most important advancement would be in making things more actionable. By actionable I am referring to making sense of the data in a way that the user can easily make decisions based on them and thus avoid being confused with the stream of information and nice charts. Maybe the software can help him make decision? Through advancements in machine learning fields and artificial intelligence I believe that this is very likely.
