For anyone who grew up in the 90s, Gwen Stefani and her band No Doubt are icons that bring back many memories.

But looking at pictures of her today, you’ll find it hard to believe that she’s now in her 50's and has still kept her killer shape.

She’s a mother of three, still sings, and is a coach on the TV show The Voice. But none of that stops her from eating healthy and exercising on a daily basis.

So, I took a look at Gwen Stefani’s exercise routine and how she approaches her diet to stay in such great shape.

Gwen Stefani's Workout Routine

Gwen Stefani's vibrant career in music and entertainment greatly shapes her fitness regimen. The high energy and stamina needed for her captivating performances necessitate a fitness routine that is both intense and flexible.

To keep up with these demands, she engages in a significant amount of high-intensity interval training (HIIT) under the guidance of her trainer, Gunnar Peterson.

While she hasn’t published details of her daily routine, her former personal trainer, Mike Heatlie, shared some details in an interview.

And it all starts with high-intensity interval training.

1. HIIT

High-intensity interval training is a form of circuit training that combines a lot of cardio and weight training work.

Here are some exercises, and you can pick 4 to 5 of them and repeat them three times.

You should also limit any rest time between sets, as the idea is to keep your heart pumping and muscles working as much as possible.

  • Dumbbell squats or barbell squats (3 sets of 12 to 15 reps)
  • Lateral raises (3 sets of 12 to 15 reps)
  • Lunges (3 sets of 12 to 15 reps)
  • Kettlebell swings (3 sets of 12 to 15 reps)
  • Stability ball crunches (3 sets of 12 to 15 reps)
  • Dips (3 sets of 12 to 15 reps)
  • Wide-grip pull-ups (3 sets of 12 to 15 reps)
  • Dumbbell curls (3 sets of 12 to 15 reps)

2. Cardio Routine

Every other day, Gwen does some form of cardio workout to keep that rocking physique:

  • Cardio boxing
  • Rowing machine
  • Running

3. Active Family Time

While she works out 5 to 6 days a week, she also spends a lot of time focusing on outdoor activities and exercises she can do with her kids.

This would involve walks and hikes, but also some water sports in the summertime.

By comparing her routine with current trends, we see a blend of time-tested methods and modern practices.

Unlike the quick-fix solutions and fad diets that flood the fitness world, Stefani's weekly regimen focuses on consistency and a mix of cardiovascular and strength training exercises.

  • Monday: HIIT and walking
  • Tuesday: Cardio boxing
  • Wednesday: HIIT and hiking
  • Thursday: Mix of running and rowing
  • Friday: HIIT
  • Saturday: Outdoor family activity
  • Sunday: Rest

Gwen Stefani’s Diet Plan

Gwen Stefani became a vegetarian when she was 12 and later committed to being a full vegan. But her eating habits go beyond just looking at whether something contains animal products or not.

Low-Carb Vegan Diet

In my experience as a holistic nutritionist, maintaining a slim and lean appearance with subtle muscle definition, like Gwen does, requires careful attention to carb intake.

This is easier said than done, but when you can limit the number of carbs you eat, then you significantly stabilize your blood sugar levels. And that reduces the stored glycogen in muscles, forcing the body to burn off more fat, according to Harvard Public Health Magazine [1].

To achieve her dietary objectives of maintaining a low-carb intake, staying well-hydrated, and ensuring a broad spectrum of vitamins and minerals, Gwen Stefani primarily opts for a selection of low-carb fruits and vegetables, complemented by nuts that are rich in healthy fats and protein.

Here’s an example of what she typically eats in a day:

Breakfast

  • Decaffeinated coffee or tea with vanilla soy milk
  • A serving of fresh fruit

Lunch

  • Vegetables
  • Nuts on the side

Dinner

  • Lasagna with ricotta cheese

Supplements

To stick with the above exercise plan, you’ll need to take a couple of supplements.

1. Protein Powder

Ideally, if you want to follow a vegan diet, choose a hemp protein powder, as it contains the full amino acid profile that your body and muscles need. Alternatively, a blend of rice and pea protein would be another go-to option to ensure you get the macros to sustain your workouts.

2. Multivitamin

Gwen takes this not just because she’s vegan but generally as a health and immune booster. Vitamins also play a key role in muscle function, exercise recovery, and effective digestion, which all lead to a leaner appearance.
