Imagine chasing a car for 2 days, that would be a killer workout. That is what happened to a swarm of bees, when they followed a SUV that had the queen bee trapped inside when it mistakenly entered the SUV at a nature center. Thousands of bees followed the vehicle as it traveled away.
What determination those bees have, when you think of giving up on your fitness routine think about your goal, just like those bees no doubt did. You can achieve great things with a little determination.
