Overview

If you have been wanting to focus on your core and strength training without overcomplicating things, this challenge is for you.

The 5-Day Core & Strength Challenge was inspired by FB Abs and designed to help you build a stronger, more stable body — the kind of strength that carries into everything you do. Whether picking up your kids, carrying bags, or training for something bigger, this program helps you move better and feel stronger through simple, effective workouts.

This isn’t just about abs or crunches — it’s about core control, stability, and total-body strength. Each day has a clear purpose, blending functional movement, strength training, and control-based core work to help you stay consistent and confident from start to finish.

Who is this challenge for?

Core and Strength is ideal for anyone who wants to build core strength and lift smarter without high-impact moves or overly complex programming. The workouts are low-impact, joint-friendly, and focused on balance and strength that you can feel in everyday life.

Whether you’re returning to training, rebuilding your foundation, or want five solid workouts that challenge you without breaking you down, Core and Strength is for you. Each workout includes options to modify or progress, so you can meet yourself where you are — and still get a great workout.

What to Expect

Each workout is 30–40 minutes long and designed to flow from one day to the next without overloading your body. You’ll train the entire core, lift heavy, and finish each workout feeling stronger, not drained. Expect structure, variety, and steady progress that adds up fast.

Challenge Layout

Day 1: Superset Core Workout
A slower-paced, focused core workout built around control, alignment, and activation.

Day 2: Heavy Strength Workout with Low Reps
Simple, heavy lifts that alternate upper and lower body to build full-body strength with low reps.

Day 3: No-Repeat Functional Core Strength
Dynamic, rotational, and anti-rotation core work designed to strengthen how you move daily.

Day 4: Total Body AMRAP Strength
Five-minute AMRAPs focused on building total body strength.

Day 5: Core Pyramid Workout
A fun, climb-and-descend pyramid workout that pulls the entire week together.

Equipment Needed

  • Dumbbells (Light, Medium, Heavy)
  • Mat (Optional)
  • Bench, Box, or Chair

Some workouts call for heavier dumbbells to challenge your strength, while others use lighter weights or bodyweight for stability and control.

Final Thoughts

This challenge is simple on paper, but delivers results when you show up and put in the work. It’s about building core and total-body strength that supports you everywhere — in training and everyday life.

You’ll move better, feel stronger, and finish this week knowing you’ve built something solid with just five well-balanced workouts designed to keep you consistent, capable, and confident.
