I am mid-50s, female, casual lifter, mostly do yoga & only lift once a week on average. Look lean but not at all bulky. I can bench 65lb, sure. Strength can be built separate from bulk. But personally wouldn’t do it alone, just in case, and honestly it would be my heavy set. For scale - Big awkward dog food bag is 45lb and most of us can wrangle that, or a 50lb bag of dirt or whatever. So it’s not a crazy heavy amount and also not crazy light.
