START DATE: December 1st, 2025

END DATE: December 28th,2025

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

THIS ISN’T HOLIDAY CHAOS — IT’S A GLOW-UP.

WHAT YOU GET WITH "SLEIGH THE SEASON"

✔️ Gym + Home Program Access for Life
✔️ 5 Workouts per Week
✔️ Video Demos + Substitutions
✔️ Tracking for Reps + Weights Inside the App
✔️ Private Facebook Group + 1-on-1 Messaging
✔️ Supportive Community

Step into the holiday ready to move, feel strong, and stay on track during the busy season.

SLEIGH THE SEASON is a 4-week challenge designed to help you train with purpose, boost your energy, and build momentum that lasts into the New Year.

WHAT MAKES THIS CHALLENGE DIFFERENT?

GYM PROGRAM BUILT FOR RESULTS

This is more than “just going to the gym.” The 5-day split is structured for maximal strength, muscle building, and body recomposition:

  • Day 1: Quads

  • Day 2: Back + Chest

  • Day 3: Hamstrings + Glutes

  • Day 4: Shoulders + Arms

  • Day 5: Core + Conditioning

HOME PROGRAM THAT STILL HITS

No gym? No problem. There are 30–45 min home workouts available to be efficient and effective using just a pair of dumbbells and a bench.
Perfect for busy schedules so NO excuses.

PS: If you're new to training, don't stress. This is actually a perfect place to start. You’ll learn proper form, build habits, and gain confidence in and out of the gym. We have people of all fitness levels join us.

ZERO GUESSWORK

Every workout is fully mapped out for you with:
✔️ Video demonstrations
✔️ In-app progress tracking
✔️ Clear instructions for each movement

BUILT-IN ACCOUNTABILITY

Rest assured that you’re not doing this alone. You’ll be surrounded by a community of people all going through the same thing — to go through the challenge together, share advice, cheer each other on and be locked in together.

We’ve got private messaging, group check-ins, and real support from me to help you get through these next 4 weeks!

HOW TO WIN

1st, 2nd and 3rd place winners will be chosen based on the top 3 final transformation results from before/after photos:

✔️ Transformation results

✔️ Participating in workouts & being a part of the community
