Does the research actually support "functional" training being superior to isolated movements, or is that more marketing than evidence at this point?
Functional training gets pitched heavily as more transferable to real-life movement than traditional isolated exercises (leg extensions, bicep curls, etc.), but looking into the actual research base, the evidence for meaningfully better real-world carryover seems thinner than the marketing around it suggests. A lot of the "functional" framing feels more like a branding shift than something backed by strong comparative studies
Interested in what people with more research background actually think here. Is there solid evidence for functional training producing better outcomes for general population goals (injury prevention, daily movement quality), or is the isolated-vs-functional distinction mostly overstated compared to just doing progressive resistance training in general, regardless of how "functional" the specific movement pattern looks?
