You can blame me for this website and the app.
I've lifted weights since starting at Worcester Polytechnic Institute in 2007, right through graduating in 2010 with a degree in Electrical and Computer Engineering. I continued picking up heavy objects and putting them back down right through my software development work at a content management company for the next seven years.
At some point during that time, I discovered squats.
The huge gains motivated me to start Plansible.
