I'm a personal trainer and after years of working out with clients this is the warm-up routine I think everyone should use

What's the best warm-up routine? That depends on your workout.

There's little point jogging on a treadmill if you're about to train your upper body. Likewise, a set of shoulder rolls and push-ups would be no use if you're about to run a 5K.
