Back to swimming

I've usually been quite reliable about my exercise routine but in recent weeks I've had an unusually difficult time motivating myself to get out of bed in the morning to go to the gym. Recently it was maybe a month since I last went for three mornings consecutively. Last week I swam every weekday morning; I don't know what changed. Perhaps something quite small suffices to tip the balance. I am cautiously optimistic about the coming week. Our membership's paid up for the summer.
