Here's a thought: Start with something you actually like, rather than a standard you used to hold yourself to. "Find something you enjoy that will prime your return to working out to be a good one," advises Fountain. "Having a good workout can boost confidence and self-esteem—key elements of getting back on the horse."
It also helps to remember all the reasons you love being in shape. "That sounds very simplistic, but it's different for each person," she explains. "I like feeling strong, and I miss that when I don't lift. Some miss the muscle pump that happens, some miss the energy they have from exercise, and some miss the mental health benefits. Figure out what you like the most and what you're missing now, and channel the desire for those feelings again to get back in there." Write those reasons on a sticky note for your bathroom mirror, or log them as an alarm on your phone so you're reminded first thing in the morning. Do whatever speaks to you most.
And then… just go. "Show up. Commit to one workout," she says. "It doesn't have to be anything daunting or overwhelming just yet, or there is a chance you fall off and feel bad about yourself for falling off—again."
