It's funny how every couple years stretching comes and goes.
I'll be blunt. Instead of asking others. Do it or dont. Record your results. Check back with me in 6 months.
Personally. I stretch for a good 60 mins. before training. + cardio warm-up + control drills.
I'm not here to say stretching prior is good. To each their own. But pay attention to most atheletes. See how much time, dedication and focus they spend on stretching.
Make your decision wisely. Don't be a lemming.
