Rather than being sat behind your computer checking out what everyone's up to on Facebook and Twitter why not get moving and check out Youtube for some great fitness videos.
Trainer to the stars Tracy Anderson has her own channel where you can follow her routines in the comfort of your own home and without the A-List price tag. Take a peek at here.
There are even videos of how to get while at your desk and pilates lessons. Just make sure to stretch correctly before and after working out and make sure you have plenty of room to move around.
