Finally not sore

On Tuesday (Mar 22 our thereabouts) I participated in a group workout that left my upper arms & shoulders very sore! We did a 30 sec work 30 sec rest circuit workout: pull-ups, jumping jacks, push-ups, supine bicycle, sit-ups, burpees, and squats. 2x. It's been at least a year since I've attempted pull-ups. I had a hard time changing clothes for the next couple of days. I was surprised my abs weren't more sore at first since I wasn't used to that much ab work either, but they got sore late Thursday. At least it wasn't all at once!
