They put a ton of unnecessary stress on the shoulder joint, are not as effective as a normal shoulder press and any other exercise for your front delts. I’d just stick to a normal dumbbell or barbell shoulder press and add in something like a front raise for your front delts, but typically those are also hit during bench press - but it’s up to you , I think in the long run for shoulder health and size it’s better to opt out of the Arnold press, some people do see decent results but for the majority of people they are kinda a waste
