What I've learnt about myself over the years is that to keep exercising regularly I need:
- Gratification, i.e. something to say "well done" when I've done some exercise (a la Strava Kudos).
- Having some fun data to play with.
- Nagging, i.e. something to keep telling me to do my exercises.
- Targets
I talked about gratification in my last Jerks post. When I do exercise, I tweet, my Raspberry Pi picks this up and sends me a Twitter DM to say "well done". Example:
When it comes to fun data, it's a virtuous circle. I exercise more and get fitter, I get more fun data. I want more fun data, I exercise more and get fitter. At the time of writing the database looks something like this:
mysql> SELECT exercise, SUM(count) FROM exercise GROUP BY exercise order by sum(count);
+--------------------+------------+

When it comes to nagging, this is what I've been working on recently. I decided to create a Python script that would periodically email with details of:
- Jerks I've done today
- Jerks I did yesterday
- Jerks I've done this week
- Jerks I've done this month
- Jerks I've done this year
- All time Jerks
The SQL for this is pretty basic, (similar to that laid out above but with date parameters). The first thing I needed to do was be able to look at today's date and calculate some other dates as offsets to it (i.e. date yesterday, date of start of week, date of start of year). Here's an example for start of week from the GetADate function (full code below):
elif (DateType == DateFirstDayOfMonth):
now = datetime.now()
DayOfMonth = int(now.strftime("%d"))
DayDelta = DayOfMonth - 1
FirstDateOfMonth = now - timedelta(days=DayDelta)
return FirstDateOfMonth.strftime("%Y-%m-%d")
This uses the "%d" attribute for strftime to return the number associated with the day of month. e.g. would return 24 for today, the 24th of January. It then uses the timedelta method (imported from datetime) with an offset of the day number minus 1 (so 23 in my example) to calculate the date of the first day of the month. This is then returned to be used in the SQL.
The email I create is formed from HTML so there's a function (CreateHTMLTable) that takes an SQL cursor as an attribute and forms a heading plus HTML table. It does this no matter how many columns or rows in the SQL response. This results in a HTML segment, albeit with no indentation.
I send the email using methods from the smtplib module. There's plenty of examples of how to do this on the interweb. I used this one from Stack Overflow that shows how to create HTML and text emails. The full code is shown below in the SendEmail function and is pretty self-explanatory. What I did find is that when I tried to use my Gmail and Outlook.com accounts to send the email, these providers did not "like" me using this method to send. Gmail blocked it out-right, telling me to lower my privacy settings to continue (which I didn't). Outlook.com kept asking me to re-authenticate my account which was a pain. I ended up using an old, unused email account from my ISP which seems to less restrictions. (It's re-assuring that Google and Microsoft have implemented these feature).
So a cron job runs the script every hour (from 8am to 10pm at weekends and 6pm to 10pm on weekdays). The email comes to my smartphone and, as I'm basically addicted to it, I pick it up pretty quickly. The first email of the day is often something like this which is a big insulting nag to do something:
...but then I get emails like this which is like "get in, did more today than yesterday":
Then I get a series of interesting summaries like these:
...and these:
Followed by a reminder of the short codes for the TUI:
So that just leaves the targets. I set these at the start of the year:
...but currently have to manually compare actuals with targets. Sounds like another Geek Dad project to create a nagging capability that includes targets...
