We've overdone the alcohol and the mince pies throughout the Christmas period and are resolving that from this week we will get back on the healthy wagon.
But despite all this, there's nothing worse than seeing slim celebrities hitting the gym - making us feel oh so guilty.
Case in point one, Nicole Richie, who got married in December so could be excused for letting it all hang out for a few months.
But the US star donned her trainers, cropped sweatpants and hoodie to work off those Christmas puds with a vengeance.
Case in point number two, songstress Alicia Keys, who may be a new mum but who isn't using that as excuse to avoid keeping in shape.
Alicia donned an all-black tracksuit as she hit the gym in NYC, making us all feel like lazy slobs for spending that extra day relaxing on the sofa.
