It’s no coincidence that your interval workouts often feel easier later in the day.  Researchers at the University of South Carolina found that people swam a 200-meeter time trial nearly six seconds faster in the early evening than they did in the morning.

 “This should hold true for any brief (five-minute) athletic performance, such as sprinting”, says Shawn Youngstedt, the study’s author.  So if you’ve been chasing a personal best, sleep in – and do your speed sessions after work. At what time do you feel is better for you?  Post a reply and share your experience!
