So, one of my PT clients on Tuesday recommended that I start my own "from the whiteboard" series. You see, during my sessions, I'll often go on a tangent during the rest periods and try to explain things like the why sum(1,...,n) = n*(n+1)/2 by mathematic induction or how a periodic function and discrete Fourier transform work, and it generally includes a lot of nonsensical scribbling, and sometimes even stick figures. Of course, these tangents do always touch back to the exercise at hand in one way (since that's what a tangent does, after all), you just normally wouldn't expect to hear that sort of stuff while working out.
My workouts are more like a physics class, rather than a birthday party, unfortunately.
And yes, I'm actually holding that handstand. Get on my level.
