Hrm he did mention that the program is suitable for everyone in general. I feel the reason that I've decided to adopt 5/3/1 is that it has a good mix in both strength and hypertrophy properties, notice the first exercises are always on low rep, higher weights than the 2nd and 3rd exercises. Also, I was previously with MadCow, doing at most 5 reps range except for the last workout session of the week. I have been with MadCow for too long that I started to get bored... Time to change to something with a lil higher reps.

Honestly I can't really give you a concrete feedback as I've just started with this program for 2 months, which isnt really a sensible duration to judge the program imho. But I can definitely tell you I am gaining mass and symmetry, which is a good thing.
