Have exercises be time + reps based, similar to how medication section works
Similar to how medication works with dosages that you click to track at a specific time, be able to add exercises or other activities, such as x reps of squats. I could click to increase to 5 reps and log it at 2pm. Another example would be something like breathing exercises, so take x deep breaths or breath for x minutes and log times completed. You can also set alarms to remind yourself to do exercises or activities, so I can remind myself to do breathing exercises at 10, 2,and 6 for example.
