clemson357 said:Exactly.
Some dude came up to me a while ago and told me I should restrict my range of motion to avoid injury. I just looked at him with a blank stare, I thought about saying something really sarcastic but didn't. After a few seconds he could see I wasn't going to respond, so he said something like "Man, I used to be a personal trainer back in the day. I aint bullshittin you are nuttin." Then I just gave him another blank stare and he left me alone.

"You are lifting at 90% of your 1RM or greater."
Neither strength nor hypertrophy will be gained from training repetitively at an intensity higher than 90% of 1RM.
Impaired Performances with Excessive High-Intensity Free-Weight Training.

The purpose of this study was to determine if 3 weeks of high relative intensity (percent one repetition maximum [1RM]) free-weight resistance training using the parallel barbell squat results in overtraining and to determine what types of performance would be affected. Six weight-trained males ( ± SD; age = 27.5 ± 5.4 year) trained 2 d·wk−1 for 4 weeks with a normal protocol (Monday, 3 ?? 10 repetition maximum [RM]; Thursday, 3 ?? 5 RM), followed by 3 weeks of high-intensity training 3 d·wk−1 (Monday, Wednesday, Friday) using 2 ?? 1 95% 1RM and 3 ?? 1 90% 1RM. A time-series study design was utilized, with each subject serving as his own control (pretest [Pre] − test 1 = normal training; tests 1???4 = high-intensity training; test 4 − posttest [Post] = recovery). One repetition maximum increased (p < 0.05) during normal training but did not change during high-intensity or recovery training (Pre = 139.5 ± 29.9 kg; test 1 = 154.6 ± 27.7 kg; test 2 = 160.3 ± 26.9 kg; test 3 = 163.7 ± 27.9 kg; test 4 = 161.0 ± 27.2 kg; Post = 161.7 ± 33.3 kg). Muscular and joint pain and soreness were not evident according to self-report training questionnaires. Also during the high-intensity phase, sprint times for 9.1 m increased (test 1 = 1.75 ± 0.12 seconds; test 4 = 1.86 ± 0.12 seconds) and peak isokinetic squat force at 0.20 m·s−1 decreased (test 1 = 2,473.2 ± 685.6 N; test 4 = 2,193.3 ± 534.5 N). In general, no changes were observed for body composition, flexibility, lower body reaction time, vertical jumps, 36.6-m sprints, lateral agility, isokinetic squat force at 0.82 and 1.43 m·s−1, or isokinetic back extension at 0.17 and 1.05 rad·s−1. Although use of single repetitions at a high relative intensity is often used to increase 1RM, this was not observed in the present study. While 1RM performance did not decrease, other performance measures were adversely affected, suggestive of an excessive use of high relative intensity resistance exercise.
One of many studies supporting use of a intensity of effort maximum at 90% or lower when training for anything more than a *few* lifts (as in max power training days for PL training, not typically employed by bodybuilders).

The role of resistance exercise intensity on muscle fibre adaptations.

Although many training variables contribute to the performance, cellular and molecular adaptations to resistance exercise, relative intensity (% 1 repetition maximum [%1RM]) appears to be an important factor. This review summarises and analyses data from numerous resistance exercise training studies that have monitored percentage fibre type, fibre type cross-sectional areas, percentage cross-sectional areas, and myosin heavy chain (MHC) isoform expression. In general, relative intensity appears to account for 18-35% of the variance for the hypertrophy response to resistance exercise.
On the other hand, fibre type and MHC transitions were not related to the relative intensity used for training. When competitive lifters were compared, those typically utilising the heaviest loads (> or =90% 1RM), that is weightlifters and powerlifters, exhibited a preferential hypertrophy of type II fibres when compared with body builders who appear to equally hypertrophy both type I and type II fibres. These data suggest that maximal hypertrophy occurs with loads from 80-95% 1RM.
Caveat- yjr asbove is true when you train like a PLer or Olympic lifter, with relatively few max effort days interspersed with fast paced, lower intensity, higher rep training days.

Obviously the exception is if you are doing a 1RM, but even then unless you have a bad back just use a squat rack. I've had to drop weights in squat racks because it was too much for me at the time and my back is fine.
