The other comment says it best. Deadlifts are a core concept are great- you can implement them into your rack pulls, trap bar deadlifts, and romanian deadlifts and reap enormous benefits that they offer.
However... Deadlifts as the exercise it is? Almost not worth doing in the scheme of things. Want to win a deadlift competition? Sure. But for any other reason I could strongly argue that there are many, many better suited exercises for your health than a Deadlift.
Deadlifts seem to be an extremely functional form of lifting movement to practice. I can see bicep curls being mocked for not providing any general benefits, or static planks not doing much except make you better at performing the static plank.
But the techniques you learn from and the muscles you strengthen doing deadlifts are the same you use when you lift a heavy box off the floor.
I do calisthenics with a goal of being healthier. It seems to be great for upper body but for lower body not so much. So I have been thinking about adding deadlifts (got from recommendations by seemingly smart people on /r/bodyweightfitness). These wouldn't be bodybuilder deadlifts, they would be didn't skip leg day deadlifts. What would you recommend as a good lower body exercise, in the not looking to get big category?
