If you're over 40 and want to build muscle, get stronger, or simply stay in great shape as you age, you might be wondering:
Do you really need to lift weights at the gym, or can a TRX Suspension Trainer get the job done?
The answer might surprise you.
Both TRX and traditional weight training can build muscle and strength. The better choice depends on your goals, experience, and which approach you'll actually stick with.
I'm Aaron Bailey, an ACE Certified Personal Trainer with a degree in Exercise Science and over a decade of experience helping people improve their fitness.
One thing I've learned from years of coaching is that you don't need fancy equipment to get great results. You need an effective plan.
Let's look at what the research says and how to choose the right training method for you.
Can You Actually Build Muscle With TRX?
Absolutely.
TRX suspension training uses your body weight as resistance. By adjusting your body position, you can make exercises easier or harder without needing dumbbells or machines.
Exercises like TRX rows, chest presses, squats, lunges, and hamstring curls can challenge nearly every major muscle group.
Here's what matters most: Your muscles need sufficient resistance to grow, regardless of whether that resistance comes from weights or your own body.
What Does the Science Say?
A 2020 study published in the European Journal of Applied Physiology compared suspension training with traditional resistance training in 42 previously untrained older adults.
After 12 weeks, both training groups experienced similar improvements in the muscle thickness, strength, and functional performance measures researchers evaluated.
That's encouraging evidence for people who prefer exercising at home.
However, it doesn't mean TRX and weights will always produce identical results, especially for more advanced lifters.
A broader 2026 American College of Sports Medicine research review, covering 137 systematic reviews and more than 30,000 participants, reinforced the benefits of progressive resistance training.
It also found that equipment type did not consistently influence training outcomes across the research examined.
The takeaway? TRX can absolutely be an effective muscle-building tool when your workouts are challenging and progressively structured.
Benefits of TRX Training
TRX offers several advantages, particularly for beginners, people over 50, and anyone who prefers working out at home.
1. You Can Train Almost Anywhere
A TRX Suspension Trainer is portable, takes up very little space, and allows you to perform a complete workout wherever you have an appropriate, secure anchor point.
No expensive home gym required.
2. You Can Adjust the Difficulty
Take a TRX row, for example.
Standing more upright generally makes the exercise easier. Moving your body into a more challenging angle increases the resistance.
This makes many TRX exercises adaptable to different strength levels.
3. You Build Strength and Body Control
Many TRX exercises require you to stabilize your body while performing a movement, challenging your muscles and coordination simultaneously.
Just remember that more instability isn't automatically better. Exercise difficulty should match your ability.
4. It's Convenient Enough to Stay Consistent
This might be the biggest advantage.
If having a TRX at home means you'll actually exercise three times per week instead of skipping the gym, that's a major win.
Want to build strength at home without guessing what workouts to do?
I created my 12-Week TRX Total Body Blueprint to provide three structured full-body workouts per week, exercise photos, progression guidelines, and tracking tools.
It's designed for beginners and intermediate exercisers who want to make consistent progress using a TRX Suspension Trainer.
Benefits of Traditional Weight Training
I love TRX, but I'm also a huge believer in traditional weight training.
Dumbbells, barbells, cables, and machines offer advantages that can become particularly valuable as you get stronger.
1. Progressive Overload Is Easier to Measure
Progressive overload means gradually increasing the demands placed on your muscles.
For example, if you're performing dumbbell presses with 25-pound dumbbells, you might eventually progress to 30 pounds.
You can easily measure and track that improvement.
TRX allows progression, too, but increasing resistance isn't always as straightforward as adding weight.
2. It's Easier to Add Heavy Resistance
Traditional weights provide an especially convenient way to keep increasing resistance.
For example, once bodyweight squats become relatively easy, adding dumbbells or using a barbell can provide a greater challenge.
This is particularly helpful for more advanced lifters or people focused on maximizing strength.
It doesn't mean weights automatically produce more muscle growth than TRX. They simply make certain types of progression easier.
3. You Have More Exercise Options
At a gym, you can select from a wide range of equipment to train different muscle groups, work toward specific goals, and accommodate individual needs.
Prefer working out at the gym?
My 12-Week Full-Body Strength Program includes three progressive workouts per week, photo guides for 21 exercises, and tracking logs to help you build strength and confidence.
It's designed to eliminate the guesswork so you can walk into the gym knowing exactly what to do.
Which Is Better for Building Muscle After 40, 50, or 60?
Here's something I really want you to understand:
Getting older doesn't mean you've missed your opportunity to build muscle.
Resistance training can improve strength and physical function throughout adulthood, including later in life.
Whether you're 40, 50, 60, or beyond, both TRX and weights can help you make meaningful progress.
Here's How I'd Help You Decide:
Build strength at home: TRX
Maximize heavy lifting strength: Traditional weights
Improve general muscular fitness: Either TRX or weights
Train while traveling: TRX
Progressively increase heavy resistance: Traditional weights
Combine convenience with gym training: Both
Ultimately, the best method is the one that matches your goals and allows you to consistently challenge your muscles.
How Many Days a Week Should You Strength Train?
According to the CDC's physical activity guidelines, adults should perform muscle-strengthening activities involving all major muscle groups at least twice per week.
Personally, I like three full-body workouts per week for many beginners and intermediate exercisers.
For example:
Monday: Full-body strength workout
Tuesday: Recovery or light activity
Wednesday: Full-body strength workout
Thursday: Recovery or light activity
Friday: Full-body strength workout
Weekend: Recovery or other enjoyable physical activity
A good full-body workout includes pushing, pulling, lower-body, and core exercises.
For many beginners, starting with approximately 8–12 controlled repetitions per exercise can be practical. Choose resistance that feels challenging while allowing you to maintain proper technique.
As your strength improves, gradually increase the challenge.
And remember, you don't need to completely exhaust yourself every workout to make progress.
The 2026 ACSM review found that training to muscular failure wasn't consistently necessary for improving strength or muscle growth.
Focus on quality, progression, and recovery.
The Biggest Mistake People Make With Both TRX and Weights
Here's where I see people go wrong.
They confuse doing random workouts with following an actual training program.
There's nothing wrong with trying a workout you found online.
But if you're constantly changing exercises, never tracking your performance, and following something different every week, how do you know whether you're getting stronger?
You might be working hard without making meaningful progress toward your goals.
A well-designed training program should tell you what exercises to perform, how many sets and repetitions to complete, how challenging each exercise should feel, and when to progress.
This applies whether you're using a TRX or traditional weights.

Frequently Asked Questions
Is TRX Enough to Build Muscle?
Yes. TRX can provide enough resistance to stimulate muscle growth, especially for beginners and people who haven't been strength training consistently. More advanced exercisers may benefit from additional external resistance for certain goals.
Is TRX Good for Beginners Over 50?
Absolutely. Many TRX exercises can be modified to accommodate different strength and fitness levels. Start with appropriate movements, a secure anchor, and manageable resistance. If you have injuries or medical limitations, seek individualized guidance.
Is Strength Training Three Times a Week Enough to Build Muscle?
Yes. Three appropriately designed full-body workouts per week can be enough to improve muscle size and strength. Your results also depend on your training effort, progression, recovery, and nutrition.
Is TRX or Weightlifting Better for Losing Body Fat?
Both can support fat loss by helping you maintain or build muscle while improving fitness.
However, body-fat loss primarily depends on your overall energy balance. As the CDC explains, physical activity combined with appropriate dietary changes can help create the calorie deficit necessary for weight loss.
Can I Combine TRX With Traditional Weight Training?
Absolutely. You might lift weights at the gym two days per week and use your TRX for another workout at home.
Just make sure your overall training volume and recovery match your abilities and goals.
Final Thoughts: The Best Workout Is the One You'll Actually Do
Here's what I want you to remember.
You don't need the most complicated workout, the most expensive equipment, or hours in the gym to start making progress.
You need a plan that challenges your muscles, fits your lifestyle, and gives you a reason to keep showing up.
That's exactly why I created two different 12-week programs.
