I love aquafit – guided aerobics in the pool. Easy to modify for whatever physical issues you have. It’s social, low pressure, and a great instructor makes it surprisingly fun. It looks really easy, and then the 80 year old ladies kick your ass at the exercises.
Pro tip: for the workday applications with the manual forms, I have a separate file I upload without formatting that perfectly fills out the forms in the fields they want, then I upload a formatted resume.
