I own a Siberian Husky. They are extremely smart, the problem is that they always want to do their own thing. So when it comes to training, you will be constantly fighting against her instincts. I've trained my Husky to do agility, but be prepared that you will first need to train your dog to obey your commands and stay with you without a leash and with dogs around. This is something that is very hard to do because Siberian Huskies always want to go.
I saw your other threads about scootering and biking. There are many ways to get your dog the exercise that she needs. The easiest is to find a buddy that also has a dog and you can let them play together. Obviously they both need to be around the same size or so if they want to 'play-fight'. I own a bike with an attachment on the side that is called a Springer, it's probably the best bike attachment there is out there. Don't order from the official website though, because they suck. Try a company called Springer America, I bought a black one from them last year and it was great.
In the winter, I trained my dogs to pull me on skis. Although they do not completely pull me, it is great exercise for my dogs. With only one dog pulling you, you will have to ski behind the dog.
For intellectual development, what better than to train tricks? Your husky will be able to master almost any trick that is on this website. The only ones I can see a difficulty with is the ones without a leash (in public places) and working from a distance. But it can be done if you are willing to comit yourself to it.
Check out the classroom, I produced many lessons featuring my own husky, even the play chess lesson!
If you are going to go to an obedience training class (which I HIGHLY recommend), then look around and make sure that they train using positive reinforcements. IE, using food rewards. You don't want to go to a place where your dog is constantly punished or disciplined. That is not fun for you or for your dog. Ask the trainer what he thinks about dominance. If he says the dog must be put in his place, look for another trainer.
