Meghan Trainor Stuns in Spider-Gwen Catsuit After 60-Pound Transformation: The Exact Routine Behind Her Fitness Reset

Meghan Trainor has sustained an impressive 60-pound weight loss by completely overhauling her approach to fitness, ditching grueling cardio routines in favor of structured strength training, intentional nutrition, and low-dose medical support.

The Grammy-winning singer turned heads across social media after unveiling a family Halloween photo dressed head-to-toe in a sleek, hooded Spider-Gwen catsuit from Marvel‘s Spider-Verse. Standing alongside husband Daryl Sabara and their three children—Riley, Barry, and infant daughter Mikey Moon—the pop star highlighted the physical payoff of a multi-year lifestyle overhaul.

The turning point did not originate on a red carpet. Instead, the wake-up call arrived when Trainor was diagnosed with gestational diabetes during her second pregnancy, prompting an urgent reassessment of her everyday health habits.

Ditching the Cardio Burnout for Strength Training

For years, Trainor believed effective fat loss required punishing endurance sessions. That mindset only left her feeling exhausted and physically inflamed.

Trainor partnered with celebrity personal trainer Bella Maher, the founder of Malibu Bodies, to restructure her training split from scratch. Together, they phased out endless miles of running and pivoted straight toward progressive resistance training and high-protein nutrition.

“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.”

By learning how to lift weights properly, the pop star built metabolic support rather than wearing down her joints through excess cardiovascular stress.

The Real Role of Medication in Her Routine

Trainor’s routine also incorporated the lowest dose of Mounjaro, a GLP-1 receptor agonist. While GLP-1 medications frequently dominate headlines as standalone quick fixes, Maher made it clear that medication was merely supplemental to Trainor’s intense dedication.

“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 is the reason this worked.”

Maher emphasized that consistent attendance, protein prioritization, and mental grit accounted for the long-term changes rather than any pharmaceutical shortcut alone.

Old Habits vs. New Routine

The contrast between Trainor’s previous regimen and her current lifestyle demonstrates why she managed to keep the weight off sustainably.

This deliberate pivot toward sustainable strength allowed the mother-of-three to keep pace with an expanding household and a demanding performance career.

Expanding Family and Navigating Motherhood

Beyond the gym, Trainor remains centered on her family life alongside Daryl Sabara. The couple expanded their brood with the arrival of daughter Mikey Moon, who was born via gestational surrogate.

Trainor has been candid about using surrogacy, explaining that comprehensive medical discussions guided them toward the safest possible path to grow their family.
