What muscles does the Sphinx work?

The Sphinx primarily targets the spinal erectors. The glutes and hamstrings work as supporting muscles.

None. The Sphinx uses your body weight only, so you can do it anywhere.

How many sets and reps of the Sphinx should I do?

For muscle growth, 3 to 4 sets of 6 to 10 reps of the Sphinx works well. For strength, use heavier loads for 3 to 6 sets of 3 to 6 reps and rest 2 to 3 minutes between sets. Add weight or reps gradually over time.
