whats a good number of reps to set for each exercise??
im currently bulking trying to gain some mass
i do sets of 8 but thinking 6 works..i dunno..should i be struggling to do my last rep on every set???

For larger muscle groups like legs, chest, back and shoulder 9-12 is plenty
For smaller muscle groups like tris, bis, calves, traps 6 is plenty

And yes you do want to be struggling on your last rep whilst maintaining strict form. keeping good form is the key to muscle growth, not pushing as much weight as possible with poor form

It will vary between people and also between muscles for the same person. Experiment for yourself to see what gives you good results.

3x10 last reps should always be very hard
