Unfortunately for all NBA fans, the Miami Heat's LeBron James will not be taking part in the dunk contest at the All-Star weekend.

But today he gave us all a little preview of what we are missing out on - with his Heat teammates seemingly equally impressed.

The video is taken from the team's practice in Phoenix today ahead of their match up against the Suns Wednesday.

And in it, we see James throwing down some pretty impressive dunks - with the gym walls getting a couple of useful assists.

While King James shows off his skills the likes of Dwyane Wade and Chris Anderson sit back and watch - with his good friend Wade even filming it just in case we missed it.

LeBron has never taken part in the dunk contest but is widely considered one of the best at the business when it comes to attacking the basket - and he just showed us all why. 

Just look at the reaction of the players as they watch Wade's replay - that is when you know you are good.
