"If you’ve got a sniffly nose or you feel a bit sluggish, a workout might actually make you feel a bit better.
"Just see how you go. But don’t go proper hardcore and do an hour workout. Do about 15-20 minutes."
6. BED BOUND
"I think it's very dependent on how you feel. But I definitley wouldn’t recommend doing a HIIT trainng session.
"If you're really, really run down or you've got the flu - rest up, and stay in bed."
7. THE DAYS YOU CAN'T BE BOTHERED TO DO A FULL WORKOUT
"Do some slow and gentle weights. It will really wake you up and ease you into it.
"Once you’ve had a bit of a chilled start with a bit of resistance work, see how you feel and maybe try a HIIT session at the end."
8. TRY AND GET A FEW GOOD NIGHTS SLEEP
"There's a strong link between the amount of sleep you get and your performance when you exercise. After a poor night's sleep you'll notice the intensity put into your workouts will decrease.
"Plus another common side effect of sleep deprivation is craving sugary foods. So your appetite will also increase and you'll want to consume way more food than you already have.
"So as soon as your head hits the pillow: steer clear of social media, turn off the TV, switch off the lights and try and get into a deep sleep."
9. WHEN YOU'RE FEELING STRESSED
"Exercise is a great cure for stress. If you’re stressed or your feeling sad; you just never regret a work out.
"You're always going to feel better, you're going to be smiling and laughing afterwards.
"I know it's hard at the time, but with all the endorphins, you can't deny how good you will feel afterwards."
10. DON'T BE AFRAID TO EAT ON CHRISTMAS DAY
"Christmas Eve onwards I crack open the Celebrations or Quality Street.
"Christmas day, I'm just grazing all day, having a big dinner and later waking up and having a load of cheese and twiglets and stuff. Oh, and ice cream.
"It’s the one day the year when I think you should just have a proper blow out.
"Don’t worry about it, it's not gonna make you fat."
11. IF YOU'RE AWAY FROM HOME
"I definitely relax on the food front but I do keep exercising, because its quite a long time. You'll have like a week off with lots of chocolate. And while it's fine to have a little indulgence, you should definitely keep moving.
"That way you don’t gain too much and just feel really rubbish come January the 1st.
"Use my Youtube channel, The Body Coach TV, for workouts you can do at whose ever house or hotel you are staying at. You don't need a gym."
12. HAVE A BOXING DAY WORKOUT
"This year I'm doing a Live Facebook Boxing Day HIIT, so that people who want to do a little workout can join me.
"People can get up, burn a few calories and have a bit more food later on in the day.
"You can feel good about yourself and then have a little binge again."
13. GO HARD BETWEEN CHRISTMAS AND NEW YEAR
"I don’t do anything New Years Day, because I’ll be drunk on New Years Eve.
"But I definitely like to keep on it in the lead up. Between the 26th and New Years Eve, I’ll workout. It just means you can balance things out."
14. STAY OFF THE SCALES
"Don’t stand on the scales before or after Christmas. What’s the point? It's gonna feel terrible.
"The weight's going go up and it wont all be body fat, it will just be bloatedness and your body storing water.
"Just track photogrpahic progress."
15. AND MAKE IT YOUR NEW YEARS RESOLUTION TO NEVER GET BACK ON THEM
"Never, ever do it! What’s the point?
"We don’t judge people by how much they weigh. We don’t pick them up and weigh them do we? You are who you are, so who cares!
"Instead take progress pictures and measurements. You know, your jeans and clothes and how they should fit you."
