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.
The basic powerlifts are Deadlift, Overhead Press, Barbell Squat, Bench Press, Rows of all sorts - and maybe accessory things like curls and tricep push-downs. Maybe Pull-ups should be on the list but I consider pull-ups and push-ups to be technically calisthenics because they are body-weight.
Of course, your body weight is plenty of weight...
You rise from a chair maybe 100 times daily, but how often do you do it with 150 lbs on your back? Never. But if you do it with 100 lbs on your back now, odds are that getting out of a chair at age 85 won't be a chore. Powerlifting is not Body-Building.
There are plenty of heavy accessory lifts with which to fill an hour, but the powerlifts are the core for strength conditioning.
So the powerlifts are not functional so much in themselves as they are designed for total body power, and muscle and bone strength. Total body strength feeds indirectly into everything you do in life except, perhaps, endurance activities. Your fitness for mostly everything, energy level, general appearance, and posture. Men and women of all ages include powerlifts in their workout programs.
Never heard curls and triceps pushdowns referred to as power lifts.
Traditionally, the power lifts are Bench Press, Squat and Deadlift, while the Olympic lifts are the snatch and clean and jerk (the press was eliminated due to problems judging the lift).
Correct use of terms prevents misunderstanding. While I understand that you probably mean strength training or compound lifts, many lifters won't.
Further, when you say total body POWER, what you are describing is really STRENGTH as power implies strength (really force) per unit of time and is a related, but different ability. Indeed, many studies indicate that it may be as or more important than maximum strength when designing programs for seniors....but that's a different topic.
As far as physical abilities, you neglected mobility. I know plenty elite lifters who were all jacked up (as in really strong, but couldn't bend over and tie their shoes) because they neglected mobility work.
Three years ago I started powerlifting at age 52. The deadlift is my favorite. Powerlifting gains will make the female form more feminine and I encourage other women to try it. The results are worth the effort!!
Headed out to go climb Mount Yonah in north GA on this glorious fall day.
