I've been recently impressed with the equipment update in my gym. Cardio machines runs smooth Android based OS. All machines equipped with NFC. It helps mobile app recognise piece of equipment for you to log the progress(need manually enter weights).
Technogym has also introduced Fitbit-like device. The differentiator is it can automatically log your gym workout sessions with the exact weights you take at each machine. The next step is a virtual couch, that would suggest machines, weights, exercises for your workout based on your previous workout data.
