Strength isn’t built when it’s comfortable. Today’s challenge: a half marathon. The first mile was just the warm-up. After that, every 3 miles meant stopping for 100 walking lunges. I’m definitely going to feel this tomorrow… but that’s exactly why I did it. How are you challenging yourself this week? #HalfMarathon #paulvancetraining #WalkingLunges #FitnessJourney #anytimefitnessberkley
