James Corden is a very funny man.
Last year he put a video together of his attempt at joining Mark Wahlberg in his gym for a very early morning workout. Hopefully it will give you a bit of a chuckle, if not inspiration.
If a new fitness regime is on your list resolutions for 2019 you might have to wake up a little earlier than you have been. But I think waking before 3 am might be a big call if you haven't been training for a while ... and if you have to work a regular job as well.
Mark Wahlberg pretty much needs to train to keep his job!
For the rest of us, though, it's more a part of being fit and healthy so check with your GP before going too hard at the gym.
Whatever your fitness goals for the year I wish you well.
