We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Barbell squats and Deads are the ultimate full- body strength builders and strength-maintainers. Middle-aged+ people, male or female, ought to do some of each weekly for bone and muscle health.
You can do deads with kettlelbells or trap bars, but there's nothing like the barbell. (There are lots of other good and useful lower body exercises, calisthenics etc., but just talking about sturdiness today.)
My view is that it's not a good idea to do more than 25-30 total working reps of deadlifts in a day's routine. That would be maybe 5-6 working sets of 3-8 reps (not counting a warm-up set). I only do deads once weekly (and barbell squats once weekly).
And, just for fun because it's not about general fitness, you can check out where your one-rep max falls - enter male or female, age, and weight. I try one-rep maxes around 4X/year, for fun. Taking age into account, I am between intermediate and advanced, which seems good for me. I can not dead 300 lbs. I blame Isaac Newton for that because he is the guy who glued the weights to the floor.
