You think it's just because I'm not used to it now?
That's a possible factor (a big one too). If your body isn't quite used to utilizing a particular muscle group, or to reach a particular output. It'll react in the form of being sore. Be glad they don't ache.
For example, you can be the strongest guy possible, but if aren't used to hitting kick serves after kick serves. Your shoulder will be sore because your rotator cuff isn't used to put up with that kind of torque/stress necessary to hit a kick serve.
