Isolation exercises are good for isolating muscles. If you want to get STRONGER and bigger, compound is the way to go.
Chill. Its diffrent strokes for diffrent folks. Virus isnt some hack the guy knows a bit what his talking about unlike most here.
The problem with what you're saying about isolation for the forearms - I've never heard a guy who can deadlift a decent amount of weight asking for help on building his/her forearms. It's ALWAYS the guys who do isolation work that complain. Same with people who do arm curls but refuse to do chinups whining about the size of their biceps. I don't see how genetics come into it. Compound lifts are superior to isolation evey time. Isolation has it's place, I'm not denying that, but for the average guy or explosive athlete isolation isn't necessary.
Rakim, since you asked for my take here it is. It depends on your goals and what point you are at in training. Every exercise has its place (well, most do) and because you cannot exactly predict how your body will react to something there is more art involved in weight training. So, they will not do you any harm to try if you want. I would also advise kettlebells.
Cheers bud. I've decided to stick with compound stuff until I actually develop enough muscle somewhere to see that another part of my body is getting left behind. Then I'll use some isolation stuff to get back in proportion. My workout must be pretty balanced at the moment because so far all my muscles are growing at around the same rate, i.e. not much at all. Cheers for all the help lads.
