It’s a good idea to guide new customers into a private community group where they can set goals and get support from mentors and others to achieve their goals.
This doesn’t just work for fitness, it works in a business context too.
When a member joins the community, encourage them to set a specific goal (ideally on their profile) which is shared with other members.
You can then connect them in your newcomer group, provide the exact advice they need to achieve the goal, and set a reward if they do.
If you want members to get familiar with your product/software fast, this is a good way to do it. Better yet, they can do it together.
