How about rows/pulling and shit from your other post?
Isolation or compound doesn’t matter: Progressively overload and you will grow: More weight, volume e.g. sets/reps per week, less rest time, better rep quality etc.
Compounds are recommended because they overload better. Adding 2.5kg either side of the bar on bench is ez. Adding 5kg to curls is hard and if you do you’re probably swinging/cheating a bit more which negates the extra weight.
So for movements where you start swinging, hip thrusting and cheating when the weight goes up an effective alternative is to add volume. If you do 12 sets of curls on week and then 14 sets the next you’ve progressively overloaded. This provides the stimulus to grow and with the right diet you’ll make all kinds of gains.
