What happens without a plan

I found some pants that were big enough to accommodate long johns, and braved the -20 degree weather to get to the gym. I didn't have a plan, and my vague notion of a circuit starting with rowing was squelched by the rare wonder of someone else on the erg. So I wandered through this mixed-bag:

Alternating sets:
Walking lunges - 25 lb x 12, 12, 12
Push-ups - 30, 25, 25

Sumo deadlifts - 55 lb x 12, 12, 12

Alternating sets:
Good mornings - 45 lb x 12, 12, 12
Presses - 45 x 8, 7, 6 (I did these just to kill time between GM sets, since I was already holding the bar.)

Rowing - 2000 m/10:20 min

V-sit ball tosses - 50, 50
