Since starting a new job earlier in the year I’ve had to make a lot of adjustments to my fitness schedule. One thing I really miss are the exercise classes I used to attend. I particularly miss the High Intensity Interval Training sessions which were a great way get a quick cardiovascular workout.
I’d been rolling my own version at home in the back garden for a few weeks and found that although these sessions worked reasonably well, I missed the class instructor who used to call out the next exercises and provide motivational commentary. Keeping track of what exercise I’ve just done gets increasingly difficult the more tired I get. I also found it annoying to have to check my watch for when to pause between exercises and re-setting a timer every 20 seconds is annoying.
Obviously it would be hard to simulate the enthusiasm of a trainer but the exercise choice and timings seemed like a straightforward thing to automate with a Raspberry Pi.
