I too am a bit dismayed in the lack of more exact precautionary directions, I’m a 6’ 212 lb male with a 4.7 abdominal aortic aneurysm under watch (6mos) and don’t lift over 50 lbs has been the mantra, I’ve even had it as vague as “don’t lift anything heavy “ I was doing an electrical job the other day and leaning forward on a ladder pushing a heavy drill upward through wood, kinda like isometric force and thinking is this ok ? I guess I’ll know at next monitor scan , I think they just use rule of thumb because there’s know way of knowing which straw it will be for each patient , I’m focusing on keeping BP low and weight reduction and I guess after next scan if larger, elimination of all straining activity , I’m sure that will be life after any repair anyway! I’ve been sky diving, kayaking, play golf sad to know a lot will change going forward
