Here are a few off the top off my head:

+Create an in-home workout program
+Add on a nutrition and lifestyle optimization upsell to it
+Create a customized, personalized at-home personal training program via Zoom
+Create an online workout course on a major course platform like Udemy, LinkedIn Learning, or Teachable.

If you need to refine these ideas more, we can talk. See my profile at https://clarity.fm/davidsanchezrn.
