I have an email account that I use solely for correspondences with clients, so I always have back ups of everything.
When I FIRST start working with someone, there is usually a good 2 week back and forth (I do mostly online coaching) getting the most detailed picture of current and past dietary and training approaches, limitations, goals, etc.
Additionally, despite keeping very detailed computer files on each person (I’m constantly putting things in charts and spreadsheets!) I always have hard copies on hand so I can more easily see what our current variables are, what they were last week, the week before etc.
If it’s a client I’ve worked with before (ie. some competitors will compete every Spring), I can pull out the week by week summary sheet from one year earlier with corresponding photos, and ensure that we’re doing better this current year.
If a client just stops showing up, or submitting updates or contacts, I will usually reach out once or twice before writing them off. I love helping people, and always instruct clients to not be afraid of blowing up my cel phone with texts (some prep clients seem to feel the need to tell me everything! -lol), but at the end of the day, I am just the guide, and if you choose not to do the work, then I can’t make you, and I won’t show up at your house and drag you back to the gym against your will. I’d much rather spend my time with people who appreciate my assistance. It’s much, much more rewarding when they thank me
