fitgingerfoodie: Dirty 30 Extreme is seriously one of the toughest workouts I've ever done! I love it though because it works so many different muscle groups and each set is a minute long. Which seems like forever when you are doing it, but seriously, you can do ANYTHING for a minute! My muscles were literally humming for a while after that! Now, time for a "recovery" run for 3 miles! I hope my sister and nephew go easy on me!! #crosstrain #dirty30 #21DFX #noexcuses #60sec #workoutwithfamily
