12 Week Strength & Sculpt

Get started today!

💪 Welcome to 12 Weeks of Body Workouts These workouts are designed to help you build strength, tone your body, and boost your fitness using my Build • Balance • Burn method You’ll train 5 days per week with the flexibility to choose 30- or 45-minute workouts, depending on your schedule. Each workout includes a warm-up and is 60 minutes or less from start to finish. Each workout has options for dumbbell only movements. Videos for those movements are listed under 'Option Demos'. This gives you a variety of options to choose from based on the equipment you have available. Every workout is built around three core components: Build, Balance, and Burn — for a well-rounded routine focused on strength, muscle growth, stability, and calorie burn. You will also see sprints and core work built in. Workout Breakdown: Each section is 15 minutes or less. You can complete 2 segments for a 30-minute session or do all 3 plus the warm-up for a full 60-minute workout. Progressive overload is applied weekly, increasing reps and adjusting loads to keep you consistently progressing. RPE (Rate of Perceived Exertion) will be used throughout the program to help you lift with intention and intensity: RPE 1–4: Very light effort (warm-up/recovery) RPE 5–6: Moderate effort (4–5 reps left in the tank) RPE 7–8: Challenging but doable (2–3 reps left) RPE 9: Very challenging (1 rep left) RPE 10: Max effort (no reps left)

Loved it. The healthy habits we were expected to follow for the four weeks were chosen perfectly, and the key to anyone having success in this challenge. Jill's Spring Shred showed just how uncomplicated it can be to feel your best, you just have to be consistent! The workouts were challenging, but so FUN! I looked forward to them every day. I also really liked the community aspect of it. Knowing these other women were busting their tails just as much as me, helped give me that push! I loved seeing their posts, showcasing how proud of themselves they were! Everyone was so inspiring!

About Jill Thornton

Online personal trainer

I’m a busy mom, body transformation coach, and founder of Breakthrough Coaching. After coaching for over 14 years, I’ve learned that the women who see real results aren’t doing anything extreme, they’re just consistent with simple habits. I used to be stuck in dieting cycles and intense workouts with little to show for it. What changed everything was focusing on realistic habits that actually fit my life. Now I help women 40+ ditch the all-or-nothing approach, build strength, and eat in a way they can stick to. No quick fixes, just real strategies to help you feel strong, confident, and in control.
