Mostly because functional strength is useful and keeps you alive. major goals as you age are avoiding falls and being able to continue doing things for yourself. Strength fits that bill pretty well (and it also improves fat free mass).
And on a slightly more technical note, recovering from higher volume becomes harder as you age, so focusing on a smaller number (5ish) of reps at higher weight gives you adaptation without quite as much stress.
But I should be clear, when I said real lifting, I don't mean to exclude any form of well calibrated progressive overload, whether that's strength focused or hypertrophy focused. I do mean to exclude the "go to the gym and lift a 10 lb weight the same number of reps each time" BS
Because hypertrophy is generally pointless compared to strength. The hyperthrophy that naturally accompanies strength work is sufficient but the strength that accompanies hypertrophy work is far less beneficial.
one of the best proxy we've for Hypertrophy is getting progressively stronger in medium rep range. (8-12)
The title says they are focused on improving body composition which is boosting lean mass, lowering of fat mass which kinda seems achieved best by focusing on Hypertrophy and fat loss?
Your strength comes both from your nervous system and physiology. Training your nervous system without also building a proper physical foundation to handle tension is a fast track to injury.
They are linked, but what I meant was its not a 1:1 relationship. You can get stronger without as much hypertrophy, or you can get bigger without as much strength gain.
The only reason I mention it is because I often see people, especially men, assume getting bigger is the main focus of getting stronger and healthier. But a more holistic approach including stretching, functional strength excercises, cardio and balance training is perhaps more important
