I know the music is a little cheesy, but I find this guy seriously inspiring. This is his progress from April 2014 to December 2016. Just shows you the value of hard work and consistency.
Question to those of you reading: who are your sources of inspiration in the BWF/calisthenics community? I like this guy, Daniel Vadnal, and Simon Ata a lot. Also, DAE just really enjoy watching training videos like these? No marketing, no talking, just pure hard work.
