rep ranges matter much?

I've been following Kevin Levrone's transformation for awhile now; for those who arent aware he was out for 4 years then came back and did video logs of each phase, mass phase, cutting phase etc....you can find it here www.levronereport.com in most of his videos I've noticed that his training is sort of situated where he'll switch his rep ranges up quite a bit and now he is in more of a strength training phase doind 4 sets of 4 trying to reach 405 and putting on solid overall size....my question is not obviously will that work for me but in general....the 8-12 bodybuilding range vs the 4-6 range....given the exact same diet which will pack more mass on the average person with all other things bein equal? especially on a bulking phase? I've been following a 8-10 rep for big body parts and 12-15 regimen and its working well but this go tme to thinkin that even most ifbb pros and strongmen have more sound muscle density with a powerlifting background etc....thnx guys:arcade:

im a firm believer in 12-15 reps

i always keepem that high no matter the weight, but then the problem at hand is finding a good spotter to keep ya goin.

i think you should hit all rep ranges and target all muscle fibers...red and white. use everything you have.

6-8 on upper body
10-15 on legs

Most of my strength gains have come in the 4-6 range. In particular a workout I only do once a year for 12 weeks.

I personally go by how my body is feeling that day...I might do lower reps if I feel extra strong that day or I might go higher reps if my pumps are crazy...It really just depends on what im body is telling me..But generally I do reps in the 12-15 range most of the time...Now I do like a higher rep range on legs, as I feel legs grow better in the 20-25 reps range on most movements....but upperbody seems to do very well on a 10-12-15 rep range for me anyway

I agree 100% however I also keep the reps that high to minimize the risk of injuring tendons and ligaments. I go up to 30 reps on some heavy exercises. I also like high reps as it makes it easier to determine strength gains. The difference between 4 and 5 reps could be anything if you are going all out. Going from 18-20 reps makes me confident of a muscle strength gain.
