Are 23kg (50lbs) baggages heavy for you?
I'm just asking out of curiosity. I'm a 27 year old woman with average lower body strength but not so strong arms (my left arm is especially weak). I have no problems lifting 23kg/50lb baggages into a car's trunk or carrying them up to an airport belt as my legs are able to assist my arms (I use a leg as a lever). However, taking the baggages out of the trunk is a different story. I always ask the taxi driver to take my baggages down as I won't be able to do so without scratching the car.
When I have multiple heavy baggages on an airport cart, I walk very fast/run while pushing the cart because walking at a normal pace would make it feel heavier.
Are those of you who are young or middle-aged able to handle heavy baggages easily while travelling alone?
