Hi Diana Vieth. Welcome to Grokker! If you are just starting back, I would suggest you join one of our programs. These will give you guided workouts for anywhere from a week to 6 weeks. Depending on your goals, interests, and current fitness level, here are a few programs I would recommend:

https://grokker.com/fitness/program/21-day-athlete/5a325cfd84c26e363dc0f5d8 - this is a 3-week beginner program, although the workouts are really good for any fitness level.
https://grokker.com/fitness/cardio/program/walk-strong-low-impact-cardio-with-ellen-barrett/5887e4e30eeec67481fa03fa - this is a 6 week beg/int program if you prefer low impact
https://grokker.com/yoga/program/yoga-basics-the-beginner-s-guide-with-celest/57dbf89c96a02c934191d5a6 - this is a 4 week beginner yoga program
https://grokker.com/cooking/nutrition-and-healthy-eating/program/21-day-nutrition-reboot/5a1c8d5075c30566d6921591 - if you are looking for some guidance on healthy eating, this has some great tips.
