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).
If you do not use a trainer, here are some thoughts about how to organize your deadlift routine: How Many Reps of Deadlifts Should I Do When I Workout
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.
