I've been training Bill Starr's intermediate 5x5 for about 5 weeks now with good results. Today however, a trainer at my gym told me not to attempt doing 3 reps with heavy weight (as per Friday's schedule), as its only helpful if I'm "very huge".
Now, I'm not very huge by any means, I'm 5'6", 64 kgs (141 lbs) and even though I don't know my body fat %, I can make a safe guess between 12 and 16%. Current 5RM maxes are bench: 125, squat: 175, row: 135, and deadlift 225 (all in pounds).
I just wanted to know whether he was right and whether I should scrap this program in favour of his recommended 4 day, 8-12 rep bodypart split.
Thanks in advance.
