The author of the article (Justin Kompf) first highlights that people’s ability to adopt and maintain an exercise program is based on two primary things;
Do they feel confident enough in their ability to be able to do the exercise?
Can they plan, manage, and monitor their exercise?
A Message A Day?
Signing up to a personal trainer is one thing but for most people, it is impossible to pay for a PT for more than once or twice a week. How then, can PTs help clients exercise more often? Enter the text message. SMS messaging and Whatsapp have made contacting clients quick and easy. A 2013 systematic-review of 10 studies concluded that text messages showed early promise for promoting physical activity. But, isn’t this something most PTs will be doing already? Maybe. If you are, do more than just do it as a token gesture. Make sure to consider the following 3 factors;
Do you know what sort of messages your clients want? Ask them. Then tailor your content. If the client lacks the confidence to carry out the exercise, motivational messages are the way to go. However, if they lack the organisation skills, these same motivational messages will be ineffective. In this instance, messages that serve as reminders, or provide a “plan B” in case something comes up in your client’s day, will be the better option.
Clients are likely to start ignore texts that feel automated. A 2015 study (2) showed that, if people found out that the messages they received were automated, they stopped reading them.
Try and find the sweet spot in how often you are reaching out to them. This is completely personal and changes from person to person. For example, while 50% of participants in one study (2) felt that 3 messages a day were too many, the other half did not feel as negatively about receiving messages this often. In another study of older adults (3), 13 of the 18 participants thought that 5 messages per week are too many and the remaining 5 thought this was fine.
If personal training clients want to exercise outside of their paid sessions, it is the trainers job to guide them, help prescribe sessions that are tailored to their needs, and then give them the confidence and organisation to see these plans through. Some of the factors laid out above should then be considered before hitting the send button on a text message. Equally, the success of these messages should be reviewed. Do they evoke the behaviour change they are setting out to help.
