Of course the pre-training routine and warm-up are essential parts of any well-rounded strength and performance program, but the overreaction to warming up in the last decade has gotten a little out of control.
For most athletes and lifters, their work capacities aren't at a high enough level where they can sustain extended warm-ups that take the better half of an hour.
When preparing to train or play, there is a sweet spot for warm-up durations.
Obviously, a well-rounded warm-up primes the central nervous system, increases tissue temperatures, enhances mobility at lagging joints, and hones movement patterns that may need a little remediation.
I know that sounds like a lot of stuff to cover in a warm-up, and that's a pitfall for most strength coaches.
If you do your homework and prescribe movements and exercises that are appropriate without all the fluff, the perfect warm-up can be achieved in around 10 minutes for most athletes.
Think about that the next time you spend 45 minutes before performing your first work set.
