I'm little ... I'm only 5' tall and weigh in a little over 100lbs...
I'm not a weight lifter, but I'm not super wimpy, at least for my size either. I can pick up and carry about 50lbs in a bag or bucket (drywall and plywood are too big for my arms though..), but a 5 gallon bucket is about 1/3 my size and depending on what's in it, 1/2 my weight. Getting the lid off can be a sweat inducing, swearing session for me.... I think they hubby listened to it one too many times and came home from a run to Cash and Carry with a lid opener one day. What a thoughtful guy
