Getting back in shape after 30

My name is Britt. I am 31, work from home as a blogger/writer/social media and digital marketer. I used to be super active and in shape, and in the past, I have taught martial arts and was a member of the Canadian Armed Forces. Unfortunately, due to some health issues, I had to take a significant step back from my active lifestyle and have gained a lot of weight over the last few years, 50+ lbs to be exact... I am not in a position to start getting up and moving again but its much harder at this stage to take it back off! Just bought myself a Garmin as a means of motivating myself and getting back on track. Looking forward to getting to know everyone on here! Ok... not everyone obviously, but at least a few of you!
