yes, low reps at a high weight are for getting big muscles, high reps and an average wieght is for endurance and strength. just depends what your looking for.
I was always lead to believe that low reps, (between1-5) high weights is used to improve max strength ,the ability to shift a heavy load. For hypertrophy, an increase in size of the muscle, you are to use a medium weight with mid range reps (between 6-12) and for endurance between (13-25 reps)
Just depends on what you wish to gain from lifting weights... also as a little side note, remember to use correct form and never sacrifice form for a higher weight... wouldn't want to do you're self any harm.
Just what I’ve herd and by the way the numbers I’ve used in there for the amount of reps may be slightly inaccurate so don't go quoting me on that, look into it for you're self on Google etc (as said above)
Hope this helps
