Building real core strength doesn't require hours in the gym, fancy equipment, or endless crunches. Over the past month, I joined Emily Saint Jacques, CPT and owner of Saint J Fitness, to guide women over 30 through five powerful core workouts designed to show up where it matters most—lifting kids without straining your back, carrying groceries with ease, and getting through long days feeling strong, not exhausted.
The full April workout series is available on the Saint J Fitness YouTube channel, so you can follow along anytime, repeat your favorites, or catch up on the ones you missed.
What You Trained This Month
Week 1 started with the fundamentals—bodyweight basics that teach you how to properly engage your core. Bear Stance Launchers built anti-extension strength, Deadbugs trained coordination and stability, Plank Taps challenged rotational control, and V-Ups brought it all together with dynamic flexion. Four exercises, 40 seconds of work, 20 seconds of rest, repeated twice. No equipment, no excuses, just you and your mat building foundational strength.
Pro tip: If Bear Stance felt tough, you're doing it right. Keep your hips level and imagine pulling your belly button toward your spine to protect your lower back.
Week 2 leveled up by adding dumbbells and combining upper body work with core stability. Dumbbell Pull-Over + Skull Crushers taught you to stabilize while moving your arms overhead; Single-Arm Sit-Ups + Shoulder Presses challenged balance and coordination; and Side Plank + Reaches on both sides fired up your obliques. The bonus Russian Twist + Press Out? Pure anti-rotation gold.
Pro tip: Don't rush the single-arm work. Slow down, feel the imbalance, and let your core do the work to keep you steady.
Week 3 introduced a game-changing pattern: 20 seconds of movement, 20 seconds of static hold, then 20 more seconds of movement. This tempo taught you the difference between moving through your core and truly owning the position. Ankle Taps to V Hold, Bear Stance Shoulder Taps to Bear Hold, Leg Raises to Scissors, and Up-Down Plank to Plank Hold. Sixty seconds per exercise, two rounds, zero equipment needed.
Pro tip: The holds are where the magic happens. Don't just survive them—breathe, brace, and feel your core working to keep you stable.
Week 4 brought kettlebell work into the rotation with Pull Over to Crunch (hello, full-body integration), Single Arm Sit Ups (unilateral strength at its finest), Plank Pull Throughs (anti-rotation meets stability), and Windmills (mobility, strength, and control all in one). This workout challenged you to stay tight and controlled as you moved a load through multiple planes of motion.
Pro tip: Windmills require patience. Start light, focus on the stretch through your hamstring and lat, and keep your eyes on that kettlebell overhead.
Week 5 closed out the challenge with controlled tempo work that prioritized quality over speed. Tempo Bicycle Crunches slowed down a classic move to eliminate momentum, Up-Down Planks built shoulder stability and core endurance, Tempo Cocoons trained full-body flexion with control, and Side Plank Elbow-to-Toe brought it home with a dynamic oblique burner.
Pro tip: Tempo training is humbling. If you're used to rushing through reps, this will feel harder. That's the point. Slow equals strong.
Your Core Challenge Wins Go Beyond the Workouts
These five weeks weren't just about sculpted abs or checking off another workout. They were about building a core that supports your real life—picking up your toddler without wincing, carrying heavy bags without compensating, standing tall after a long day at your desk, and moving with confidence in your body.
The women who showed up consistently didn't just get stronger. They learned how to breathe under tension, how to modify when needed, and how to trust their bodies to do hard things.
