Tonight's show will feature a live trial, Jungle Gym.

All celebrities will be eligible for the trial.

With the world gone exercise mad, Jungle Gym will be I’m A Celebrity’s interpretation of an exercise routine.

One lucky celebrity will be able to work out on the ‘Death Row’; revive themselves with a shake - full of ‘critermin c’; and relax afterwards in the I’m A Celebrity ‘Sore-na’.

All celebrities will go to public vote to see who will undertake the worse exercise regime they have ever seen.
