What Is Body Recomposition (And Why It Works After 40)?
If you’re over 40, you’ve probably noticed that fat loss feels harder and muscle is easier to lose.
Body recomposition is the process of building lean muscle while reducing body fat at the same time—and it’s one of the most effective approaches for women in this stage of life.
This isn’t about starving yourself or doing endless cardio. Instead, it focuses on two key processes:
• Muscle protein synthesis (building muscle)
• Fat burning (reducing stored body fat)

Why Women Over 40 Need a Different Approach
Hormonal changes (like declining oestrogen) can affect:
• Muscle mass
• Fat storage (especially around the midsection)
• Insulin sensitivity
• Recovery
This means your plan must be smarter, not just harder.

How to Build Lean Muscle
1. Strength Training with Progressive Overload
Resistance training is essential—especially over 40.
Focus on progressive overload, gradually increasing weights or reps over time.
Prioritise compound exercises:
• Squats
• Deadlifts
• Rows
• Presses
These movements help maintain bone density, improve metabolism, and build strength.

2. Protein Intake & Amino Acids
Muscle growth requires all 9 essential amino acids, especially leucine, which triggers muscle protein synthesis.
👉 Recommended protein intake:
1.5–2g per kg of body weight
This becomes even more important over 40, as the body becomes less efficient at using protein.

How to Lose Fat Without Damaging Your Metabolism
1. Caloric Deficit (The Right Way)
To lose fat, you need a caloric deficit—but not an extreme one.
Crash dieting leads to:
• Muscle loss
• Slower metabolism
• Hormonal imbalance
👉 Instead, aim for a small, sustainable deficit.
⸻
2. Metabolic Adaptation
If you’ve dieted before, you may have experienced weight loss slowing down.
This is due to metabolic adaptation, where your body:
• Burns fewer calories
• Increases hunger
• Holds onto fat
👉 Solution:
• Avoid long-term extreme dieting
• Combine strength training with nutrition
• Include maintenance phases

Macronutrients for Women Over 40
Balancing macronutrients is key:
• Protein: Maintains and builds muscle
• Carbohydrates: Fuel workouts and energy
• Fats: Support hormone health
👉 Many women under-eat protein and over-restrict carbs—this can backfire.

The Importance of Insulin Sensitivity
Improving insulin sensitivity is critical for fat loss over 40.
When insulin sensitivity is high:
• Your body uses carbs efficiently
• Less fat is stored
• Energy levels improve
You can improve it by:
• Strength training
• Eating whole foods
• Reducing processed sugar
• Sleeping well

Why You Need Periodised Training
Training hard every session isn’t the answer—especially over 40.
Periodisation helps you:
• Avoid burnout
• Recover properly
• Continue progressing
It involves adjusting:
• Volume
• Intensity
• Load
• Recovery

Best Training Method: Daily Undulating Periodisation
For women over 40, Daily Undulating Periodisation (DUP) works extremely well.
It varies intensity throughout the week to support recovery and progress.

3-Day Workout Plan for Body Recomposition
Monday – Strength Focus
• 5–8 reps
• 85–90% of 1RM
• Rest: 2–3 minutes
Goal: Build strength and muscle density
⸻
Wednesday – Hypertrophy (Muscle Building)
• 10–12 reps
• 65–80% of 1RM
• Slow tempo
• Rest: ~60 seconds
Goal: Increase muscle tone and shape
⸻
Friday – Endurance & Fat Loss
• 12–15 reps
• 40–60% of 1RM
Goal: Increase calorie burn and metabolic stress
⸻
Rest, Recovery & Hormonal Balance
Recovery becomes even more important after 40.
👉 Prioritise:
• 7–9 hours sleep
• Rest days between sessions
• Stress management
Overtraining increases cortisol, which can promote fat storage, especially around the abdomen.
