Android/iOS: Having a goal to work out more is fine, but it's hard to prioritise when other things come up. Google Calendar can now help by letting you set goals that will automatically work around your schedule. The new feature rolling out today allows you to pick a goal you'd like to work on regularly, like working out or practising a skill. You can then set how often you want to do it, for how long, and choose the best time of day to work on it. Calendar will then automatically find open slots in your schedule for them.
As you add items to your schedule, Calendar will automatically adjust as needed. Suddenly have a meeting pop up in the afternoon when you normally work out? Calendar will bump it to after your meeting. If that's too late, it will push it to another day. If you just can't work on your goal when it comes up, you can defer it and Calendar will reschedule it to later. It's a handy tool for things that you definitely want to schedule time for, but can't guarantee a specific time you need to do it.
