Is a adjustable dumbbell patented?

Short answer: specific designs of a adjustable dumbbell have been patented many times, but "a adjustable dumbbell" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a adjustable dumbbell been patented?” but “has my combination of features been described before?” Health and fitness devices are dense with sensor and wearable patents; compare the sensing method, mounting, and what feedback is given.
