Pop star Meghan Trainor has always looked stunning and amazed fans with her striking new look after completing a year-long fitness transformation that left her fitter, stronger, and more confident than ever. The 30-year-old Grammy winner, known for hits like All About That Bass and Mother, has been working with Malibu-based personal trainer Bella Maher as part of a full lifestyle overhaul focused on strength training, mindful eating, and structured routines.
Maher shared a series of before-and-after gym photos on Instagram on Sunday, October 26, taken a year apart, showcasing the singer’s impressive progress. The side-by-side images from 2024 and 2025 quickly went viral, drawing admiration from fans and fellow celebrities.
Maher wrote on Instagram, “Watching her transform from the inside out has been one of the most meaningful parts of my work. She did so much of this on her own before ever introducing a GLP-1, and even after starting it, the medication was simply a support, not the reason for her results. GLP-1s can be a powerful tool, but they're certainly not a transformation plan.”
She added, "SHE is the reason this worked Meghan prioritised strength training, protein, intention, structure, and showed up even on the days she didn't feel like it. She built this. She earned this. And now she gets to live in a body that supports her for life. I am so proud of you, my girl.”
Earlier this year, Trainor reflected on her fitness journey during an interview with Entertainment Tonight. She said: “I learned a lot of tricks that I had no idea about. I was working out so incorrectly for so long. I was running and doing cardio and my body was inflamed, always.”
Never one to lose her sense of humor, she added: “So anything that'll help me age backwards, I'm into it. I just learned about the NADs. I was like, ‘Make me Hailey Bieber. I'll do it, I'll take it.’ I'm trying all the things. I love a doctor explaining stuff to me.”
She told Parents magazine in 2023: “I think when you have a kid you just realise, wow, life is beautiful and precious. I want to be the best for my kid. I've never been more motivated. I look at Riley and think, I'm going to do anything I can to live forever.”
Social media users flooded comment sections with praise, calling her transformation both physical and emotional. Many described her as an “inspiration” for finding balance between self-acceptance and wellness.
