Why Muscle Building Over 40 Matters
- Slowing Muscle Loss: Around 40, muscle mass naturally starts to decline. Strength training reverses this trend.
- Boosting Metabolism: Muscle burns more calories than fat, even at rest. More muscle = faster metabolism.
- Protecting Joints: Strengthening muscles supports joints, reducing wear and tear.
- Improving Quality of Life: From carrying groceries to playing with grandkids, staying strong makes everyday activities easier.
Key Principles for Safe and Effective Muscle Building
- Focus on Form First: Perfect your technique before adding weight.
- Prioritise Recovery: Muscles take longer to recover as we age. Include rest days and quality sleep.
- Warm Up Thoroughly: Dynamic warm-ups prepare your muscles and joints, reducing injury risk.
- Progress Gradually: Increase weights slowly to avoid overloading your body.
- Eat Enough Protein: Aim for 1.6–2.2g of protein per kg of body weight daily to support muscle growth.
10 Tips to Boost Metabolism After Your 40s
The 5 Best Muscle-Building Moves for Over 40
1. Heels-Elevated ATG (Ass-to-Grass) Front Squats
- Why It Works: Encourages full range of motion, improving joint health while targeting quads and glutes.
- How to Perform:
- Elevate your heels on small plates or wedges.
- Hold a barbell across your shoulders, keeping your chest tall.
- Squat deeply, keeping knees aligned with toes.
- Perform 3–4 sets of 8–12 reps.
- Pro Tip: Reduce the weight by 10–15% on your final set to focus on form and take the set to failure safely.
2. Single-Arm Tripod Rows
- Why It Works: Targets back muscles with low complexity, allowing for heavy yet safe lifting.
- How to Perform:
- Stagger your feet with one hand on a bench for stability.
- Pull a dumbbell towards your hip, squeezing your shoulder blades.
- Alternate arms every 75 seconds for 3–4 sets of 8–10 reps per arm.
- Pro Tip: Use lifting straps to prevent grip fatigue and maximise back activation.
3. Snatch-Grip Romanian Deadlifts (RDLs)

- Why It Works: Stretches and strengthens hamstrings, while the wide grip challenges upper back stability.
- How to Perform:
- Use a wide grip on the barbell, hinge at your hips, and keep your back flat.
- Lower the bar to just below your knees, feeling the stretch in your hamstrings.
- Perform 3 sets of 8–10 reps.
- Pro Tip: Use lifting straps to maintain grip and focus on form.
4. Incline Dumbbell Bench Press
- Why It Works: Builds chest, shoulders, and triceps with a focus on shoulder-friendly angles.
- How to Perform:
- Adjust the bench angle from 45° to 15° across three sets.
- Lower dumbbells slowly, pause at the bottom, then press up.
- Perform 3 sets of 8–12 reps.
- Pro Tip: Lower the incline as you fatigue to continue lifting effectively.
5. Hanging Leg Raise Complex
- Why It Works: Strengthens the core, enhances grip strength, and improves shoulder mobility.
- How to Perform:
- Start with 5 cross-body leg raises per side.
- Follow with 5 traditional leg raises.
- End with a 10–15 second isometric tuck hold.
- Complete 3 rounds.
- Pro Tip: Use ab slings if grip strength is a limiting factor.
Essential Warm-Up Routine

- Bike Warm-Up: 5 minutes of cycling to increase body temperature.
- Box Lateral Step-Downs: 2 sets of 10 per leg to activate lower body muscles.
- Face Pulls: 3 sets of 15 with a resistance band or cable machine to prepare shoulders.
Nutrition Tips for Muscle Growth
- Prioritise Protein: Include lean meats, eggs, fish, tofu, or legumes in every meal.
- Healthy Fats: Avocados, nuts, and olive oil support joint health.
- Complex Carbs: Oats, brown rice, and sweet potatoes provide lasting energy.
- Stay Hydrated: Muscles need water to perform and recover.
Recovery Strategies
- Stretching: Focus on hamstrings, quads, and shoulders post-workout.
- Foam Rolling: Release tension in tight muscles.
- Sleep: Aim for 7–9 hours nightly for optimal recovery.
