Also could be that you just naturally use your back muscles more in your daily life so they are not as shocked by the workout.

This. I probably lift back 4-5 times in any 14 day span. I trained biceps twice all of last year, because I get a better bicep workout constantly hitting back than any amount of single-joint movement curl workout.

For the OP, since it was your first day back doing those workouts, it was probably better to go with a lighter weight for 10 reps.
