Trinny Woodall believes fitness should fit into life, not the other way around.
That philosophy shines through in her latest arm workout, shared on Instagram with coach Nathalie Hayward.
At 62, the fashion entrepreneur proves you don’t need fancy equipment or a gym membership to build strong, sculpted arms.
Just two water bottles—or even cans of chopped tomatoes—and nine straightforward exercises done at home.

Why Trinny’s Approach Works
Woodall has trained with Hayward since 2020, developing a routine that prioritizes consistency over complexity.
You don’t need an expensive gym membership or an intimidating set of weights to get your blood pumping. Two water bottles (or even cans of chopped tomatoes) are all you need. You will feel infinitely better for having moved your body and taken a few minutes to reset.
Her workout video demonstrates exactly how to execute each move with proper form, making it accessible for beginners while still challenging enough for seasoned exercisers.

The session starts with four mobility exercises to prepare the upper body, then transitions into five targeted strength moves.
Gently start, and it’s amazing how quickly you’ll see it work.
The Complete 9-Exercise Arm Routine
Mobility Section: Prime Your Shoulders and Spine
These four movements wake up joints, improve range of motion, and reduce injury risk before the strength work begins.
1. Cat-Cow Stretch
Start on hands and knees. Inhale as you round your spine upward. Exhale as you arch it downward.
Hayward explains this mobilizes the spine while expanding the backs of the ribs, which directly improves shoulder mobility—crucial for upper-body exercises.
2. Quadruped Arm Circles
From the same position, extend your right arm forward with thumb pointing up.
Inhale and lift the arm, then exhale while sweeping it back in a wide semicircle. When you can’t reach further back, rotate the arm and bend at shoulder and elbow, pulling back. Return to start.

This creates full shoulder rotation, opening up the joint capsule before loading it with weight.
3. Plank to Downward Dog
Extend legs into a high plank position. Bend knees and push hips backward into a modified downward dog. Return to plank. Complete three repetitions.
Can’t hold a full plank? Hayward suggests pushing back into child’s pose instead, then returning to hands and knees.
4. Quadruped Thoracic Rotation
Reach left arm forward. Place right hand behind head. Inhale as right elbow drops to the mat. Exhale as you rotate the torso, opening the chest toward the ceiling.
Hayward calls this a “true thoracic rotation,” targeting the mid-back area that often gets stiff from sitting and poor posture.
Strength Section: Build Arm Muscle at Home
Now the real work begins. Grab those water bottles or light dumbbells.

5. Alternating Bicep Curls
Stand with shoulders back and down. Curl one weight up using either a classic (palms up) or neutral (palms facing each other) grip. Alternate sides.
It’s really important that we don’t swing the weights too much, so we’re not relying on momentum. We’re really working the front of the arm here.
Control is everything. Slow, deliberate reps build more strength than rushed, bouncy movements.
6. Bent-Over Reverse Fly
Hinge forward at the hips with a flat back. Open arms to the sides—not overhead—keeping them slightly behind your body.
This targets the rear deltoids and upper back, muscles often neglected in arm workouts but essential for balanced shoulder strength and posture.
Struggling with the hinge? Hayward recommends sitting on a chair or bench instead, maintaining the same arm movement pattern.
7. Lying Tricep Extensions
Lie on your back, feet flat. Hold weights with arms extended above shoulders. Bend elbows, lowering weights toward your head while keeping upper arms stationary. Extend back to start.

Squeeze the backs of those arms.
The triceps make up roughly two-thirds of upper arm mass, making them critical for anyone wanting defined, strong arms.
8. Forearm Plank
Drop to forearms in a plank position. Hold for 10 seconds if you’re new to this, working up to 45 seconds as you build endurance.
Planks simultaneously work shoulders, arms, and core—maximum efficiency in minimal time.
9. Dumbbell Upright Row
Stand holding weights in front of thighs. Lift them toward your collarbone, keeping wrists straight. Pull shoulders back slightly as you lift to avoid neck strain.
This final move targets the middle deltoids, creating that rounded shoulder look. Aim for 10-12 repetitions.
We’re going to do the whole thing twice.
Two full circuits deliver a complete upper-body session in under 20 minutes.

Why This Workout Design Matters
Woodall’s routine follows sound exercise principles: mobility first, then strength work targeting all major arm and shoulder muscles.
The balanced approach—hitting biceps, triceps, shoulders, and upper back—prevents muscle imbalances that can lead to injury or poor posture.
Research consistently shows that resistance training is vital for maintaining muscle mass as we age, particularly for women over 50 who face accelerated muscle loss.
Building and preserving arm strength isn’t just about aesthetics. Strong arms make everyday tasks easier—carrying groceries, lifting grandchildren, opening jars, pushing doors.
Upper-body strength also protects joints and bones, reducing fall risk and supporting long-term independence.
Making It Work for You
Start with whatever weights you have. Seriously—water bottles, canned goods, or 2-3 pound dumbbells all work.

Focus on perfect form before adding heavier resistance. Hayward’s cues throughout emphasize controlled movement over speed or load.
Can’t complete all the exercises? Modify as suggested or skip the challenging ones initially. Consistency beats intensity when building a sustainable routine.
Perform this workout 2-3 times weekly for best results, allowing at least one rest day between sessions for muscle recovery.
As movements become easier, increase weight gradually—even jumping from water bottles to 5-pound dumbbells creates meaningful progression.
The Bigger Picture
Woodall’s approach removes the most common barrier to fitness: complexity.
No commute to a gym. No intimidating equipment. No elaborate setup.
No products found.
Just clear instructions, minimal gear, and exercises that deliver results when done consistently.
Her partnership with Hayward since 2020 has clearly paid dividends, evident in her strong, capable physique at 62.
That relationship highlights another key factor: having guidance matters, even if it’s through a screen rather than in person.
The mobility-before-strength sequence, the attention to form cues, the modifications offered—these details separate effective programming from random exercise selection.
Woodall proves that home training can absolutely build meaningful strength when designed thoughtfully and executed consistently.
No excuses needed. Just grab those water bottles and get started.
