Im not an ectomorph, thats for sure. This is my POV to become stronger. I always believe that a trainee can never neglect Bodybuilding movements, the rep work etc. I have been neglecting BB work and have been focusing on low rep work which is a bad mistake and I've only recently incorporated BB work in my routine. The basic 3 is also vital, Deadlifts, Squat and Bench. I can't put myself off by saying I'm a bad bench presser, I bench not as heavy as I squat and deadlift and I think this shows that how much bb work that I lack all this while.

Workouts like Cable Rows, Lat Pulldowns, Barbell Rows , Leg Presses and other BB movements should never leave a trainee's list regardless of their goals, strength or physique etc.  A strong back will significantly improve your Squats, Bench, and Deadlift. Your leg might be able to handle a 200kg backsquat, but can your back handle the weight? So is deadlift, can you maintain that strong arch when pulling a 180kg for 5 reps for instance. In terms of bench press, can you keep your back arched strong? See how much role does the back plays?

This is how I approach my routine, Low Rep demonstrates strength, High Reps improves strength. This shows that one cannot stick to low reps all the time, maybe once a month to see where you at in terms of strength. Other than that, keep the reps moderately high.

This might be a little long winded for you so I decided to stop here at the moment. Remember, this is my POV on training, and I just realized I've made a huge mistake to ditch BB work so you shouldn't do the same.

Good advice. My coach I think gave the best way to summarize this;

Go heavy, go high reps.

When we train, we never actually follow a particular system. We'll see what our weaknesses are at. Then we'll work at it. Then when it gets easy, we play with the repetitions. Higher rep for this set, add a bit more weight for the next set, pause at certain points, use chains to overload, use bands to assist in speed, use deadstop squats. All sorts lah

Stop kidding yourself lah.
WE're one of the most arrogant bunch of gym rats in Malaysia yet half of us won't even make it pass stage 1 of a bodybuilding contest. We're essentially the true definition of elitist gym rats. No wonder we're still skrawny fucts that still worship a 200LBS bodybuilder
