Consulting a personal trainer when looking to optimize ones athletic abilities and performance is the usual approach for sports enthusiasts to take, but the 'Fitstrap' back sensor is intended to completely change this.
The sports wearable works by being positioned onto the lower back and will immediately go to work detecting the movement of the user in order to let them know when they are in the optimal position. The unit will vibrate to let users know they aren't in alignment, which will discreetly allow them to make adjustments as needed to get back on track.
The 'Fitstrap' back sensor works with the accompanying smartphone app to let users track their performance, compete against others and more.
