Runners & Yoga Tip:
Before your Yoga or Pilates stretching class, complete your training run for the day and time the end of your run to finish just before class begins. Your muscles will be very warm and you will get the most out of your class.
Stretches should be held at least 40 seconds to a full minute and Orthopedics will recommend you hold the stretch a minimum of 60 seconds. Yes, that amount of time will seem like an eternity, however, to get the muscle elongation that is required, you must hold those stretches.
