START DATE: March 10, 2025

END DATE: April 20, 2025

OPEN TO: Women & men of all fitness levels, worldwide

No matter where you're starting from, this 6-week challenge is designed to push past limits, build lean muscle, burn fat, and create a fitness routine that actually sticks. Whether you’re hitting the gym or training at home, you’ll follow a clear, proven structure to see real, lasting results.

ALL NEW HOME WORKOUTS – No more skipping workouts because life gets busy. These revamped, high-efficiency sessions take just 30-45 minutes and require only a pair of dumbbells—so you can train anytime, anywhere without sacrificing progress. The structure includes a mix of circuits, EMOMs, and core finishers, keeping workouts challenging, effective, and never boring.

GYM PROGRAM BUILT FOR SERIOUS RESULTS – This strategic program isn’t just about going to the gym—it’s about training with purpose. Expect a balanced mix of heavy lifting, hypertrophy work, and accessory movements to help you build curves, sculpt lean muscle, and get stronger than ever. The workouts will start with strength movements, and end with an EMOM, core finisher, circuit, etc. If you're ready to train hard, push limits, and see insane results, this is for you.

**HEY, REAL QUICK -- don't be intimidated. If you're completely new to the gym space, this is a great place to start --let me help you form the habits and make the gym part of your routine)

NO GUESSWORK – Everything is mapped out for you so you can focus on progress, not confusion. Every movement includes a detailed video tutorial to ensure proper form and technique. Plus, substitutions can be provided so you can adjust for injuries, equipment availability, or personal needs without missing a beat.

COMMUNITY & ACCOUNTABILITY – You won’t do this alone! You’ll be surrounded by like-minded, motivated individuals who are going through the exact same process as you. They’ll be there for the ups and downs, to complain about tough workouts with you (lol) but also to celebrate every win, push through low points, and share ideas. This isn’t just a program — it’s a support system.

$2000 CASH PRIZES TWO winners will take home $1,000 each. Prizes based on top transformations **must follow all photo submission guidelines*
