@Alexander Halford and
@Anna C, if I may weigh in on this:
How much rest you take between swings and getups will depend on how you do each and what your goals are. The program, "by the book", does not require a long rest between swings and getups or that they be broken into separate sessions, but there are variables to consider. E.g., if this:
[a] hundred swings (... usually leaving me with my tongue on my shoulder)
then the first thing we should say is that you may not be following the directions - you're supposed to own the weight, and work on owning the weight, and not push yourself hard except perhaps when you're testing, and even then, we hope it's not that big a stretch for you to complete.
The "own the weight" idea goes hand in hand with daily training - this isn't a program where you're supposed to greatly tax yourself and then recover but the opposite, one which you approach like your job, which might leave you a little tired but not more than that.
But having said that, if you choose two sessions per day, one for swings and one for getups and any other strength training, I don't think you'll be doing yourself a disservice, and your getups will feel stronger because you'll be fresher, and I don't think there's anything wrong with that, either. But I'm talking about leaving a few hours between swings and strength training, and not relegating each to its own day. But even then, if you have reached your S&S goal and are scaling it back to accommodate other activities, then you are really the master of your own schedule and should do your swings and getups in a way that helps and doesn't hinder your other activities, and if that's doing swings and getups on separate days, that's fine, IMHO.
JMO.
