The “Secret Strength” Method: Can Training Your Tendons Make You Stronger?

There is a form of strength training that is getting more attention lately.

It is called tendon training, connective tissue training, or even the “secret strength” method.

The idea is that instead of focusing entirely on building larger muscles, you also train the tendons that connect those muscles to your bones.

You may have seen videos of people preaching this method all over the web, some of the claims may even go too far.

However, there is something interesting behind the trend.

Your tendons are really an important part of how you produce and transfer force, and training them could be useful in the long-run. Let’s dive in deeper in today’s blog!

Your Muscle Are Not Doing All The Work

During lifting, it is easy to think that your muscles are doing all of the work.

You feel your biceps during a curl or your quads during a squat, so naturally that is where most of the attention goes.

But muscles do not move your bones by themselves.

Tendons connect muscles to bones and transfer the force muscle produce. They also have the ability to store and release elastic energy, almost like a spring.

The Achilles tendon is a great example. Every time you walk, run or jump, it is repeatedly loaded and unloaded. It helps your body use energy efficiently and contributes to the ability to push off the ground.

All of this means that tendons are heavily involved in keeping everything together. They are part of your strength system.

Can Tendon Training Really Make You Stronger?

Short answer, yes. But, probably not in the way some YouTube videos suggest.

Training your tendons will not suddenly make you twice as strong without building muscle along the way.

Your muscles still produce most of the force.

But improving the capacity of your tendons can help your body handle and transfer that force more efficiently.

Tendons respond to mechanical loading. With consistent resistance training, they can adapt to the demands placed on them.

This is particularly important because muscle and tendon adaptations do not always happen at exactly the same speed.

You can become noticeably stronger in the gym within a relatively short period of time, but your connective tissues may need longer to adapt to the new loads.

This is one reason why gradually increasing resistance is so important.

Isometrics: One of The Simplest Ways to Train Tendons

One of the biggest parts of the tendon-training trend are isometrics.

An isometric exercise is simply a contraction where you produce force without moving the joint.

A good example is the humble wall sit.

Your legs are engaged heavily, but you are not repeatedly moving up and down.

The same principle can be used with a plank, a static squat hold, a dead hang or holding a weight in place.

These exercises can create tension without requiring constant movement. For tendon training, that makes isometrics particularly interesting.

They allow you to expose muscles and connective tissues to a controlled amount of force with a gradual increase over time, to make things more challenging.

And you don’t need complicated equipment as well.

A wall, a pull-up bar or a pair of dumbbells can be enough to get started.

Slow Repetitions Are Another Option

Tendon training is not strictly limited to one position.

Slow, controlled strength exercises can also provide a useful stimulus.

For example, a simple body-weight squat. Instead of dropping quickly and bouncing back up, you could take three or four seconds to lower yourself before standing again.

You can do the same thing with lunges, calf raises or pull-ups.

The goal isn’t to make every workout painfully slow, but to increase control and provide enough stimulus for overload.

You will see, a basic exercise suddenly becomes much more challenging for both your muscles and tendons as well.

Some of The Best Tendon Exercises are Ordinary

You don’t need super fancy exercises to start incorporating tendon training into your workouts.

In fact, some of the most useful movements are probably already familiar to you.

Wall sits are an easy way to introduce isometric loading to the legs.

Calf raises can progressively load the calfs and Achilles tendon.

Lunges and split squats challenge the muscles and connective tissues around the knees and hips while also requiring balance and control.

Planks create impactful tension through the trunk and shoulders.

Dead hangs challenge the grip, forearms and muscles around the shoulders.

Finally, farmer’s carries are particularly interesting because you are essentially walking while maintaining a strong isometric grip and stable posture.

These aren’t secret exercises, the difference is how you use them.

You can hold a position for longer, increase the resistance, slow down the movement or gradually move toward more difficult variations.

That is progressive overload, in the sense of tendon training.

Tendons like consistency

One mistake people can make after discovering tendon training is assuming that more is automatically better.

It actually isn't.

Tendons adapt to loading, but they generally do not appreciate sudden dramatic increases in workload.

If you have not been jumping, running or doing heavy calf work for months, suddenly adding hundreds of repetitions because you want to “strengthen your tendons” is probably not the best approach.

Start with a manageable amount, and give your body time to adapt.

Then gradually increase the resistance, duration or difficulty.

This might seem less exciting than the extreme routines you see online, but it is much more sustainable.

And tendon training is something where patience can be particularly valuable.

 

Why this could be especially useful as we get older

There is another reason I find tendon training interesting.

As we get older, maintaining muscle strength is obviously important. But being able to use that strength is just as important.

Walking up stairs, getting out of a chair, carrying groceries, hiking or catching yourself when you lose your balance all require your body to produce and control force.

That involves much more than muscle size.

Regular resistance exercise can help keep the entire system accustomed to loading.

This is where simple exercises such as calf raises, wall sits, squats, lunges and carries can become surprisingly valuable.

You don't need to train like an athlete.

You simply want your body to remain capable of handling the physical demands of everyday life.

Conclusion

Considering everything, tendon training is not a “secret strength” method.

However, it is a very useful form of training that deserves more attention.

We spend too much time talking only about building stronger muscle, while giving much less attention to the tissues that connect those muscles.

That doesn’t mean you should stop lifting weight or trying to build muscle. It means you can look at strength a little differently.

Real strength isn’t just about how much muscle you have. It’s about how well your entire body can produce, transfer and control force. And tendons are a part of that equation.
