Have you thought about exercising in chunks?
Instead of doing one workout, consider breaking exercise into bite-size pieces or snacks.
For example, you can move for 15 minutes in the morning, 15 minutes at lunch, and 15 minutes in the evening.
Move a little bit at a time. Move a little bit each and every day.
Small chunks add up. Breaking exercise into segments or sessions may make working out more manageable and help you stick with it.
