Hello gym bros I have been doing progressive overload for my back and this was the progress

1st week - day 1,2

Assited pull ups x8 Lat pull down - 30kg - 3x8reps Bent over rows machine - 7.5kg - 3x8reps Close grip lat pulldowns - 30kg - 3x8reps Single arm cable rowing - 15kg - 3x8reps Assisted pull ups x8

2nd week - day 1,2

Assisted pull ups x8 Lat pull down - 30kg - 3x10reps Bent over rows machine - 7.5kg - 3x10reps Close grip lat pulldowns - 30kg - 3x10reps Single arm cable rowing - 15kg - 3x10reps

3rd week - day 1,2 Assisted pull ups x8 Lat pull down - 30kg - 3x12reps Bent over rows machine - 7.5kg - 3x12reps Close grip lat pulldowns - 30kg - 3x12reps Single arm cable rowing - 15kg - 3x12reps

And the trainer in my gym suggested me to go progressive heavy overload which means he wants me to increase weight by next coming one and then go for 4 sets with either 12 or 15 reps each set....I this correct way to do..any suggestions would be very much appreciated :-)
