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.
(It's funny/sad to recall, but we were all also tested on our singing ability, math ability, and public speaking ability. Whew. As a 13 year-old nature-boy nerd, I guess, all was deeply humbling. Humbling is good for the soul, mostly.)
Keep in mind that a pull-up (palms away from you) is different than a chin-up (palms toward you). Chin-ups involve the biceps to a much greater degree while pull-ups work the lats more.
I'm not sure how a bench press, which works the triceps pretty hard, would be used to balance out other triceps stresses. Chin-ups work the biceps enough that curls are not generally necessary (unless you really want to curl, of course). Chin-ups are still superior to curls because they are a full body exercise (everything is moving), rather than the single joint as in a curl.
Nope. Curls are body building as they focus solely on one joint, one muscle, while pull-ups are much more general strength builders.
Some hard things are better than others. Sure, a heavy set of curls is hard, but not nearly as good for you, or as efficient at building strength, than a hard set of deadlifts or squats. Unless you are a body-building, 'curls for girls' type, curls are a waste of valuable gym time. You get much more bang for your buck by doing pull-ups.
It's like the guys who do bench presses with their feet off the ground to make it 'harder'. You know what else makes bench harder? Putting another plate on the bar. Which also has the advantage of actually making you stronger, which the feet in the air position cannot do.
I used to do dips thinking that they were a good triceps and part chest builder but I would always have some shoulder pain. After reading through The Physics of Resistance Excercise I discovered the reason for the shoulder pain. While dips do work the triceps and chest the muscles that get the most work are the front deltoids. https://novaxmandate.org/
