Your first challenge...

...are situps/crunches!

Today, complete 25-50 situps or crunches, or more if you can manage! Do them all at once, or in sets throughout the day.

Don't forget to Tweet/Post your achievement - use hashtag #sweatyadvent

Once complete, treat yourself by checking out Heidi's pledges and blog for some more inspiration.
