2019 Bikini Body Challenge: 30-Day Sculpting Workout Plan

Ready to feel confident and look your best for swimsuit season? Join a group of motivated women working toward the same goal. Our annual Bikini Bod Challenge brings together supportive, like-minded participants who use macro-based nutrition and positive accountability to lose weight, tone up, and boost confidence. Strength truly is in numbers—many of our past participants tell us the community support is the reason they succeed.

This six-week challenge is open to any woman who wants to drop a few pounds, tighten up, or simply feel healthier and more energized. Whether you already count macros or are new to the approach, you’re welcome to join. You may be surprised how much progress and how much more confident you’ll feel after six weeks. Below are the full details and what to expect:

  • $20 entry fee to participate
  • After payment, participants receive instructions and a link to the private Facebook group
  • $500 grand prize awarded to the most impressive transformation
  • Stay Fit Mom macro coaches will select the winner on June 4th
  • Post your before photos in the private Facebook group by Monday, April 22nd at midnight to be eligible for the prize (photos may also be emailed to [email protected])
  • The $20 entry fee covers group participation only and does not include a bespoke macro plan; you can use a free macro calculator online or purchase a custom macro plan directly from Stay Fit Mom
  • Participants can also receive $20 off the Stay Fit Mom Guide to Counting Macros on Your Own or the upcoming 6 Week Online Macro Coaching package when they sign up for the challenge, effectively offsetting the entry fee

Take a look at last year’s transformations to see what’s possible when you combine a sustainable nutrition approach with consistent support and accountability. The results are real: many women report clearer energy, better sleep, improved strength, and visible changes in body composition.

Before and after transformations

This private Facebook group focuses on macro nutrition—tracking protein, carbohydrates, and fats to meet personal goals—but following the macro diet is not mandatory. The group exists to support a range of approaches, whether you track rigorously, follow a flexible plan, or simply adopt healthier habits and better portion control.

Throughout the six weeks we use the group to stay accountable: members share before photos, set clear goals, exchange easy recipes, post macro-friendly meal ideas, offer tips for tracking, and celebrate milestones together. Coaches contribute guidance on form, nutrition tips, and motivation to help you stay consistent. The atmosphere is encouraging, practical, and family-friendly—designed to fit the busy lives of moms and women balancing multiple responsibilities.

How to prepare: take clear before photos, write down realistic goals for the six-week period, decide whether you want to calculate your macros independently or purchase a custom plan, and be ready to participate actively in the private group. Consistent check-ins and willingness to try new recipes or simple workouts will amplify your results.

We’d love to have you join our community and take part in a positive, motivating challenge that helps women feel stronger, healthier, and more confident in their own skin.
