I have a membership at the local leisure center and go swimming there, but have never ventured upstairs to the gym. I've been putting off starting but I don't always have time for a swim, so end up doing nothing when I could have fitted in 30 minutes or so of land based exercise. I went to book an induction, thinking it would be next week or longer, and I could procrastinate some more, and it tomorrow!
What's likely to happen?
What do I wear/take?
Do I change there or go in exercise stuff?
