Meghan is motivated by being a mother. "I think when you have a kid, you just realize, 'Wow, life is beautiful and precious. I want to be the best for my kid.' I've never been more motivated," she told Parents. "I look at Riley and think, 'I'm going to do anything I can to live forever.'"

She Lost One Pound Per Week

According to Meghan, slow and steady wins the weight loss race. She told People that she lost weight "the healthy way, the long way, the one pound a week way," she said. "And it's a proud accomplishment that I never thought I could ever do."

She Pays Attention to Portion Size

While she hasn't divulged specific details about what she eats, Meghan has said that she eats as healthy as possible and understands the importance of eating in moderation. "I learned that I do like healthy food, and I learned what portions mean," she told Entertainment Tonight Canada.

Meghan told Entertainment Tonight Canada that she was committed to daily exercise. "I was like, 'If I can survive a C-section, I can do anything.' And I did," she said. "I was very dedicated, and I started seeing the pounds come off one week at a time, one pound. I was like, 'I'm fighting.'"

She Got Strong for Her Tour

Meghan was also motivated to get strong for her The Timeless Tour this fall. "I'm feeling fit. I've never been so fit," she told People. "I already told my household. I was like, 'I am training for the Olympics, okay?' I want to train and eat clean, and feel good when I'm dancing and singing."

Strength Training

Meghan's workout of choice is strength training. Her trainer, Rebecca Stanton, recently shared a video of the two at the gym together. Their session consisted of lots of squat and lunge variations and using free weights doing lots of slow reps.

She Doesn't Focus on Numbers

"Because I've seen so many people on TikTok now open up, and I'm like, 'Here's what it looks like to be 180 pounds.' Everyone's body's so different," People. "You could see a girl who's really tall in a bikini, showing off her 185 pound body or something. And I'm like, 'Wow. It's so interesting how weight sits differently on everyone.' Numbers are just numbers. Whatever makes you feel the healthiest is where you should live."

She Has Dabbled in the Paleo Diet

A few years back, Meghan told HollywoodLife that she was following the caveman style diet. "I'm working out! I'm trying to be healthy. I eat all Paleo and I learned smaller portions," she said.

She Doesn't Weight Herself

"I can't get on that scale," Meghan told Hollywood Life. "It's like — you gain muscle weight and you're like, 'what's going on?.' So [I'm] just living life. I'm just trying to be happy and eating healthy foods. I know when I eat something bad I have a horrible stomach ache and it's just poison. I can't eat stuff like this!"

She Does Workout DVDs

Trainor is a fan of at-home workout DVDs, specifically Shaun T's video series called Insanity. The videos are 25 minutes long and each focuses on something different — for example cardio, ab intervals, or total body circuit training. She called the method "amazing."
