I'm fatter, weaker, and tighter than I've ever been, and have decided it is stupid to try to make major changes in my golf swing until I make major changes in my body. I'm a data nerd and like to quantify/measure everything I can, and I'd like to be able to chart my progress in this endeavor. Weight is obviously easily tracked (and body fat%), and strength lends itself to measurement, but what's the best way to measure my flexibility and mobility, particularly golf related? If anyone has any resources or ideas, I'd appreciate the help.
Thanks in advance.
