What's the best time of day to stretch?
Sports Performance answers
The correct answer, of course, is whenever you can fit it in. But here's a secret: Nothing beats a little stretching before bed. Static stretching will sustain the flexibility earned from your pre- and postworkout stretches, and the nighttime sessions will release tension built up from your busy day by signaling your body to shut down for the night, helping you fall into a deep, regenerative sleep.
Create a nightly habit of stretching your hamstrings, followed by your back and shoulders, and you'll sleep like a log.
