Do you really need extra protein after exercising, (bars, shakes and so on)?

Polswedgirl
I am at the gym 4-5 times a week, some days I do cardio and some weights lifting or group training. I also have a personal trainer hour once a month, so I guess you could say I take my training pretty seriously. I've heard a lot that people who work out a lot "need" to buy extra protein to gain muscles faster and so on. I want to hear your opinions. Should I buy a protein bar or a shake after working out? Is it really necessary? it will be pretty expensive for me if I should buy a bar or shake every time I work out.. Do you buy protein powder/shakes/bars? And why, why not?

Thank you all for sharing your opinions, it's really helpful and interesting. I think I'll skip the supplements... Maybe I'll just eat after the gym (meat/fish something with a lot of proteins).. :)

I'm afraid the bars are almost as sugary as sweets so..
