Don't worry Huskies are VERY intelligent.
(one of mine taught himself to open LOCKED windows !!!)
They love mental stimulation as much as physical exercise.
Train one trick, when they start getting bored, or appear unresponsive,move onto something else.
Also, especially Sit, Lay down and recall needs to be trained and practiced out on walks too.
They can be invaluable if they get off lead. If they only do these in the home they may not respond to them as well out doors.
Just be aware that no matter how well or often they do something,
If they don't want to do it they won't.
