Watch UFC strawweight champ Joanna Jedrzejczyk SMASH the pads during training

JOANNA Jedrzejczyk has a well-deserved reputation as one of the scariest strikers in the UFC.

Weighing in for her fights at 115lbs, the Polish striker is the smallest champion on the UFC roster.

But her lightning quick hands and venomous punches mark her out as one of the most devastating strikers in any weight class.

And if you’re looking for evidence, look no further than her latest Instagram video, in which she showcases her blistering hand speed as she batters the mitts in a breathless training session.

Jedrzejczyk takes on rival and fellow TUF coach Claudia Gadelha in an eagerly-anticipated rematch for the Pole’s UFC title at the The Ultimate Fighter Finale on Friday July 8.

The pair have already had an all-out brawl in the UFC Training Center after the cameras were packed away at the end of filming of the current season of The Ultimate Fighter.

And the rivalry remains as hot as ever as the duo get set for their world championship showdown at the MGM Grand next month.

If her intensity on the pads is anything to go by, Gadelha is going to have to put in the performance of her career if she’s going to force ‘Joanna Champion’ to change her nickname.
