Wow.
I added 2 inches to my abdomen and waist and subtracted 2 from my shoulders and chest, in order to estimate where I was before summer started, and it gave me 17.98 - I guess it IS accurate! My coach estimated me at 18% just before school got out. And 2 inches added to my chest is conservative - ever since working KB presses, chins, bent rows and full dips my back and especally my lats have jacked up.
Even I am finding it hard to believe that I did this with only a kettlebell, chins and dips, no dieting, and achilles tendon bursitis(which meant less kettlebell work for almost 2 weeks). At this rate 12 hours of baseball a week for college (starting a week from tomorrow) will wipe my bodyfat off the map!
