1. She Only Exercises When She Wants To

Michelle doesn’t force herself to go to the gym. "If I really, really don’t want to go - I don’t go," she told Cosmopolitan UK. She does try to work out three times a week for 45 minutes, but sometimes skips her workouts. "I just don’t punish myself, it’s not, like, my life to go to the gym. If I can go to the gym I will, if I can’t, I can’t," she said. "I think the more you go, the more you guilt trip yourself because you feel like it’s part of your routine. If I can go four or five times a week, great. If I can only go twice - or once - at least I’ve been."

2. She Avoids Carbs at Night

Michelle tries to eat her carbohydrates earlier in the day. "I try not to eat carbs late at night," she told Cosmopolitan. "I hate that feeling of feeling really full before going to bed."

3. She Prefers Weights Over Cardio

"I hate cardio. I just hate that feeling of not being able to breathe," Michelle revealed to Cosmopolitan. "A few years ago I would have done about 40 minutes of cardio, whereas now I feel like the more I do weights, the more I see a change in my body. For my body, weight training is better for me. I do alternative days, so one day I’ll focus on my legs, and the next day I’ll focus on my arms.”

4. She Switches Up Her Workouts

"I never do the same thing. I change it up all the time," she added to Cosmopolitan. "I’ve started doing HIIT exercises before I do any weights now, and I actually really enjoy [it] because I feel like I’ve done something. I’ve sweated before I’ve even got onto the weights." For inspiration, she even puts on different HIIT workouts on YouTube.

5. She Doesn’t Eat Red Meat

Michelle doesn’t eat red meat, but it isn’t a health decision. "I’ve never really liked the taste, ever," she told Cosmopolitan. "I’ve never been one to go out and have a steak, I’ve never craved it. Even with a roast dinner, if my mum would serve lamb or beef, I’d always leave it to the side. A few years ago I did a photoshoot with a lamb and that just threw me, it put me off lamb." She has mostly cut dairy out of her diet. "It's hard because I like cheese, but I’m trying not to have any milk in my coffee so I’m using alternative products like coconut milk and almond milk," she explained.

6. She Allows Herself Cheat Meals

Michelle allows herself to cheat without any guilt. "I love a good cheeseboard, I also love a Chinese on a Saturday night," she told Cosmopolitan. "I never feel guilty when I eat cheat food because if I’ve been quite strict all week, I feel like I deserve it. I never feel guilty if I eat a cheat meal. I’m a proper foodie, I love my food."
