I usually don’t do traditional static stretching after a speed-power workout. I’ll do it after recovery or general fitness workouts but even then it’s more yoga type (with focus on breathing) or fascial stretching methods. I will occasionally do it following speed-power workouts if I think that the workout or preceding workouts will necessitate it or external circumstances (long bus / plane rides, lots of life stress, etc). In these cases, I’m actually more likely to do a ‘choice stretch’ routine where I recommend the athletes pick a prescribed number of stretches. Generally, they stretch what needs to be stretched (if anything actually needs it) and even if it doesn’t it provides some training program autonomy which is relatively important in my opinion.
