Small swing set, only 400. I plan on a long walk tonight, and since I didn't get swinging until late, I didn't want to wear myself out before my walk. Anyway, mostly single transfers, alternating between the 8kg and 12kg, but I did manage one set (a minute) of two handed swings with the 16kg! I haven't touched that one in awhile, and I typically would only do sets of maybe 10 at a time. So, 40 in a row is a lot, for me! It was burning for sure!
