Haha tightness is a side effect yes…But I stretch religiously every morning, before a track session, and at night. So practically twice a day.
Id rather listen to you guys…better advice than most coaches.
Oh and after my first track workout on Monday after 6 months, I was sore as a mofo because I havent sprinted on real track/grass for so long. Its just artificial training on ellipticals or treadmills or stairclimbers.
