im startin a bulkin diet, and would like some suggestions on my lifting routine.
should i

1: lift heavy and less reps, say 6-8,

2: medium weight and 8-12 reps,

3: light(still pushin myself) and 12-15 reps

which is the best to achieve the best possible muscle growth, my body type is ectomorph so find it very hard to achieve any growth, i also work in a physically demanding job job, if that has anything to do with it
