Think building muscle after 40 is too late? Think again. Age may slow things down a bit, but your body is still fully capable of gaining strength, improving posture, and staying lean well into your 40s, 50s, and beyond. The trick is doing the right moves consistently and with smart technique.
In this post, we’ll cover the 7 non-negotiable exercises for building muscle after 40. These are the foundational movements your body needs to stay strong, mobile, and injury-free. Whether you’re a beginner or getting back into fitness after years off, these exercises will help you move better and feel stronger than ever.
Why Strength Training After 40 Is Essential
As we age, muscle mass naturally declines. This process, called sarcopenia, can begin as early as your 30s and speeds up over time if you don’t train. Losing muscle leads to weaker joints, more fat gain, slower metabolism, and a higher risk of injury.
But here’s the good news—resistance training helps reverse that loss. Building and maintaining muscle after 40:
- Increases metabolism
- Improves balance and stability
- Protects joints and bones
- Boosts testosterone and growth hormone naturally
- Enhances posture and energy
The key is focusing on compound, functional movements that recruit multiple muscles at once.
Let’s get into the 7 non-negotiable exercises you should be doing now.
1. Squats
Squats are a must for building strong legs and glutes. But they also improve core strength, posture, and daily movement patterns like sitting, bending, and climbing stairs.
How to do it:
- Stand with feet shoulder-width apart
- Keep your chest up and back straight
- Lower your body like you’re sitting in a chair
- Drive through your heels to stand back up
Muscles worked: Quads, glutes, hamstrings, core
Why it matters after 40: Helps prevent knee pain, improves hip mobility, supports walking and lifting
Variations:
- Bodyweight squat (beginner)
- Goblet squat (hold a dumbbell or kettlebell)
- Wall squat with support
Start with 2–3 sets of 10–12 reps.
2. Push-Ups
Push-ups are one of the best bodyweight exercises for upper body strength. They strengthen your chest, shoulders, arms, and core in one movement.
How to do it:
- Place hands slightly wider than shoulders
- Keep body in a straight line from head to heels
- Lower until your chest nearly touches the ground
- Push back up without sagging hips
Muscles worked: Chest, shoulders, triceps, core
Why it matters after 40: Builds functional pushing strength, supports joint stability, improves posture
Variations:
- Wall push-ups (easiest)
- Knee push-ups (moderate)
- Full push-ups (advanced)
Start with 2 sets of as many reps as you can with good form.
3. Bent-Over Rows
Rows target your upper back and posture muscles, which often get neglected in desk jobs or sedentary lifestyles. They also help balance out the pushing from push-ups.
How to do it:
- Hold dumbbells with palms facing in
- Hinge forward slightly at the hips, knees soft
- Pull the weights toward your waist, squeezing shoulder blades
- Lower slowly with control
Muscles worked: Lats, rhomboids, rear delts, biceps
Why it matters after 40: Supports spine alignment, prevents shoulder injury, strengthens pulling strength
Variations:
- Resistance band rows
- One-arm dumbbell row on a bench
- TRX or suspension rows
Do 2–3 sets of 10–15 reps.
4. Deadlifts
Deadlifts are the king of full-body strength. They strengthen the entire posterior chain, including glutes, hamstrings, back, and core. This lift mimics the motion of picking things up off the floor, making it extremely functional.
How to do it:
- Stand with feet hip-width apart
- Hold dumbbells or a barbell in front of thighs
- Hinge at hips and lower weights while keeping back flat
- Drive through your heels to stand tall
Muscles worked: Glutes, hamstrings, lower back, core
Why it matters after 40: Reduces risk of back injuries, improves daily lifting tasks, strengthens hips
Variations:
- Dumbbell Romanian deadlift (easier)
- Barbell conventional deadlift
- Kettlebell sumo deadlift
Start with 2 sets of 8–10 reps.
5. Planks
Core strength isn’t just about visible abs. A strong core supports your entire body, protects your spine, and improves balance. Planks are one of the best ways to build core stability without straining your lower back.
How to do it:
- Get into a forearm plank position
- Keep body in a straight line
- Engage your glutes, abs, and thighs
- Hold for 20–60 seconds
Muscles worked: Core, shoulders, glutes, lower back
Why it matters after 40: Supports posture, reduces back pain, improves functional movement
Variations:
- High plank on hands
- Knee plank (easier)
- Side plank (for obliques)
Start with 2–3 rounds, hold as long as you can maintain good form.
6. Lunges
Lunges are essential for leg strength, coordination, and balance. They train each leg individually, which helps fix imbalances and prevents joint stress.
How to do it:
- Step forward with one leg
- Lower your back knee toward the floor
- Keep front knee in line with your ankle
- Push back up and switch legs
Muscles worked: Quads, hamstrings, glutes, calves
Why it matters after 40: Improves hip mobility, boosts balance, strengthens knees and ankles
Variations:
- Reverse lunges (easier on knees)
- Walking lunges
- Dumbbell lunges
Do 2 sets of 8–10 reps per leg.
7. Overhead Press
To round out your upper body, include an overhead press to build shoulder strength and upper back stability. This move improves your ability to lift items overhead without strain.
How to do it:
- Stand or sit with dumbbells at shoulder height
- Press weights straight up over your head
- Lower with control back to shoulders
Muscles worked: Shoulders, triceps, traps, core
Why it matters after 40: Enhances joint mobility, builds shoulder support, helps daily lifting tasks
Variations:
- Seated dumbbell press
- Resistance band overhead press
- Single-arm press for more core challenge
Start with 2–3 sets of 8–12 reps.

FAQs About Building Muscle After 40
Can I still gain muscle after 40?
Yes. It might take a bit longer, but your muscles can grow at any age with proper training, nutrition, and recovery.
How many days a week should I strength train?
Aim for 3 to 4 days of strength training per week, with rest or low-impact activity in between.
Do I need supplements?
Not necessarily. Focus on real food, including enough protein, veggies, and healthy fats. If needed, protein powder or creatine can support muscle growth.
Is cardio still important?
Yes, but it’s not the priority for muscle building. Do light cardio like walking or cycling 2–3 times a week to support heart health.
What if I have joint pain?
Modify exercises, reduce load, and consider working with a physical therapist. Resistance bands or lighter weights can help keep you moving safely.
