Chances are you were lifting the toddler or sandbag with ho hum form. You aren't going to hurt yourself lifting 50 pounds like that. You try ho hum form with 400lbs on a barbell and your body is not going to be very happy with you.

Does ho hum mean bad? Couldn't really find it, just that it means routine/dull. But if good form, then I find it unlikely that you hurt yourself with 400lbs if you progressed to that.
