Keep an eye on your posture. It's easy to develop a permanent hunched-over position from riding a lot.
I do standing dumbbell curls after riding, where I focus on a straight back and perfect posture and form as I lift. I think it helps activate the muscle memory of standing up straight, which is easily lost if you spend a lot of time on the bike, especially if you're older and prone to hunching over more, due to age.
