The Light Show

One of the coolest features of the Smarter Exercise Toolkit app was inspired by the advanced equipment design at Ren-Ex.  I had attended the Ren-Ex Future of Exercise Conference in 2012 in Cleveland, Ohio.  Doug McGuff  was the keynote speaker. Ken Hutchins, principal author of the SuperSlow exercise protocol, was also a presenter. Ten years ago, Ken certified me and our original staff as SuperSlow instructors when we all visited his facility near Orlando, but I digress…

The Ren-Ex equipment provides immediate visual feedback to both exerciser and trainer.  It does this by using digital force gauges to stream force data through a computer monitor positioned in front of the exerciser.  The slightest distraction shows-up on screen, providing immediate feedback.  Needless to say, the immediate feedback aids self-learning while demanding total mental focus, improving safety, and cranking-up exercise intensity.

The Ren-Ex equipment is brilliant, but it also comes with a hefty price tag.  If you can buy it, buy it!  After three years, I still have ambitions of purchasing my own Ren-Ex machines, so please buy my app so I can use the proceeds to keep my studio state-of-the-art.

It occurred to me that not everyone, me included, will have access to Ren-Ex equipment.  But maybe, just maybe, since most of us are carrying around smartphones with built-in accelerometers, we could come-up with a poor man’s – I mean, more universally accessible – application of Newton’s equation: f = ma (force = mass * acceleration) in order to provide immediate feedback to an exerciser.

I call it the light show… using data streaming from your device’s built-in accelerometer, yellow and red warning lights will indicate when excessive acceleration is detected during an exercise.  The immediate feedback aids self-training while demanding complete mental focus, improving safety by helping to eliminate excessive forces, and helping the exerciser to crank-up the intensity.
