This scene is increasingly common in training gyms:

Coach Jim Johansen, Mountain Shadows Gymnastics Camp
There are moments when you want to show an athlete something, quickly and easily. More often than not a coach pulls out a camera or phone and takes a low resolution, short video clip.
It’s far more convenient than walking back to the gym office to pick up the camcorder.
Expert video coach Don Eckert at Woodward West Camp was the first I’ve seen using an iPhone in the gym. He loaded up the 8Gb of memory with some of his most useful video clips. The bright screen (and “coolness” factor) is very popular with gymnasts and coaches.
