Fly, Fly, Fly like a Butterfly...never really swam much as a kid but this is certainly one of the most effective exercises to stay lean, strong, and injury-free as one is older. Taught myself the butterfly stroke thru trial, error, and repetition. It still ain't perfect but been awesome to see and feel the results from powering thru workouts with it... ??? #StayStrong #BeFit #innerstrength #discipline Thanks for the pic ? @btonelli
