I recently heard a BBC Radio 4 program about Life tracking ( they had a fancy title, Quantifying self). While listening I was thinking HOLY CRAP, thats me.. my whole life is recorded - whether pictorially through Facebook or Instagram, textually through here or tumblr and fitness wise I will go into below. I recently have been trying to shift some KGs after hitting my highest weight without much effort! (mid 80kgs)
As you are probably aware, I am a gadget man, the first item that grabbed my eye was the new Fitbit Flex.
Basically its a Bluetooth Enabled Pedometer which doubles as a sleep tracker.
The wrist based device 'gameifies' the process of basically moving your body. In default setting of 10000 steps as a goal per day the device shows one single light per 2000 steps, providing vibration feedback when the 10000 is reached. The crowning glory of the divide in my opinion is back end - the app tracking and recording.
More recently I have added the Aria - the wifi enabled scale that perfectly couples with the Flex and the Fitbit app, not just measuring KGs but also lean body mass.
For the record - am now in the 70kg range.
