Is it different to train 2-5 reps and 8-12 reps

[Willmogulater]

I don't understand the difference let's say i pick a weight which I fail at say 4 reps or i pick a weight which i fail at 9 reps whats the difference if I increase reps either I will get stronger right
So recently I have been strength training like low reps but the issue is it's hard on lower back and joints + cns fatigue cause everyday u have to spend 2 hrs at the gym and lift heavy asf which is taxing as a natural lifter

Let's say if I do the training with 8-12 rep ranges why is it not beneficial, imo strength training is good but very high chances of injury as it's taxing on body and naturally body takes time to heal overtime the small issues creep up

I have now changed my program to do 8-12 rep ranges still pushing to failure

depends whether you want more muscle or more endurance

Both maybe lifting heavy is fine but what about stamina what about flexibility I been doing strength training but that just make body stiff I'm confused

do cardio for stamina
do calisthenics and mobility training for flexibility

and also stretching will improve flexibility but that one should be water

lower rep ranges focus more on strength while higher ranges target endurance, though both build muscle. to fix the body stiffness, you just need to add stretching and mobility work to your routine.
