Joined a gym - gotta get fit

Just joined a local gym - after 2 years off it is time to get fit again. It has been 12 months since my surgery, so I no longer have any physical excuse. It is just a matter of getting into a routine and living through the first few weeks (I know that the first few weeks feel really bad). I know it is good for adhd to get regular physical activity - I just need to focus (hahahaha).
