You've prepared every detail of your class down to the second and you're excited to share your active brainchild with others. As participants trickle in and you greet them, you notice that many are gazing at their phones, while others seem to be light years away. Can they hear you? Is the microphone working? And perhaps most important: Since so many of them appear to be not fully present, will they be able to navigate your rich and layered choreography without getting hurt?

Information overload is becoming a major force in modern life. We're constantly bombarded by tweets, bells, alerts and check-ins on our smartphones, tablets and smartwatches. Our mental real estate is littered with texts, reminders, news, updates and much, much more. All this, compounded by life's ongoing responsibilities, can scatter attention far and wide. You don't have to teach a mind-body-oriented class to see the need for a transition from digital distraction to your highly focused routine. What can you do to help attendees—at least temporarily—shift from tech-driven mind chatter to 100% present-moment awareness so they fully absorb your cues on how to safely execute a box jump? The following tips may help.

Set the Tone

Warmups aren't just about preparing the body; they set the tone for the entire class. Your warmup is the perfect time to do something that signals a move from one space (the outside world or digital distraction) to your class. Martica Heaner, PhD, a health writer and fitness expert based in New York City, plays a dramatic opening song in her cycling classes to help riders "zone into the workout and out of their real worlds."

Los Angeles— and Zurich–based fitness expert Shirley Archer, JD, MA, 2008 IDEA Fitness Instructor of the Year, teaches classes that include a lot of moms, so she doesn't like to dictate whether they can use their phones or not. However, she does ask people to put their phones on silent and to leave quietly if they must. "I also start classes with a temple bell or bowl followed by a sensory warm-up where we check balance and posture with eyes closed," she says. This brings everyone into the present moment and gathers the group energy."

Provide a "System"

It may be useful to have a predetermined system in place upfront so that people know what the expectations are. Make it clear you're not trying to punish anyone, but rather you want people to have the safest experience possible. 2009 IDEA Fitness Instructor of the Year June Kahn, owner of June Kahn's Bodyworks LLC, Broomfield, Colorado, asks her Pilates students to put their phones on silent and drop them in a basket by the door. "If someone absolutely needs their phone (emergencies only), I request that they put it on silent (not vibrate) and put it under the reformer, where it is out of sight. While teaching Pilates, I emphasize complete concentration, and when they [engage that way], it amazes me how those who absolutely have to have their phones by their sides get so wrapped up in the moment that they never glance at [their devices]. It's a start."

Hyperfocus on the Workout

Another way to get participants fully engaged is to focus on what you want them to do instead of what you don't want them to do. In other words, instead of pointing out that someone is rapidly developing "tech neck" while he stares at his phone, highlight the workout with full gusto. Peter Twist, MSc, president and CEO of Twist Performance + Wellness, Vancouver, British Columbia, doesn't allow phones in training areas and teaches programs that inherently demand attention. "The exercises are designed to force people's brains to compute nonstop," he says. "No one who is participating could use their phones even if they wanted to. Those who have snuck their phones in stop participating and leave the room."

Whatever method you use for helping participants disengage from their phones and align with your workout, be clear why you have guidelines and make sure they match those set by your facility.
