Beyond the Gym: How Cellular Science Is Influencing the Future of Fitness

How do you get fitter without spending more time working out?
It sounds like a biological impossibility. Except that science isn't laughing.
Billions of people struggle to get enough exercise, which means billions more could probably use some help staying healthy without adding more strain to their lives.
Meet the oral exercise mimetic.
1.8 billion adults globally were insufficiently active in 2022. Which translates to roughly one out of every three people on Earth failing to reach guidelines set by the WHO.
What if we could trick the body into thinking you just worked out?
Here's a look at some cool new cellular science…

What Is an Oral Exercise Mimetic?
In simple terms, an oral exercise mimetic is a compound that triggers the physiological changes your body would normally produce during exercise.
Consider this: when you finish a hard workout your body doesn't just tire itself out. Signals cascade throughout your system directing almost every major organ to become more efficient at running mitochondria, generating energy, and fighting inflammation.
The concept of the oral exercise mimetic is to unlock those signals without having to log the hours in the gym.
Some of the most promising compounds identified to date (like SLU PP 332, for example) function as ERR activators. Activating ERRs drives many of the same molecular pathways that prolonged endurance exercise does. Instead of pushing your body athletically, you'd be pushing it on a cellular level.
The results appear to mimic traditional exercise at the most basic level.
Got a lot to unpack here, so let's dive in…
The Biochemistry Behind Exercise
We've got to start at the mitochondria.
When someone exercises regularly and with enough intensity their mitochondria become more efficient at generating energy. Tissue after tissue rebuilds itself to be able to produce more energy, clear out toxic byproducts, and resist stressors like inflammation.
That's what creates healthier bodies.
Nobody doubts the importance of exercise. But the biological exercise response is MUCH broader than most people understand.
One recent study from the Broad Institute discovered exercise induces changes in the way 19 different organ systems operate at a molecular level.
Improvements to exercise capacity start at the cell.
Mitochondria are responsible for turning the nutrients we eat into energy. They also play a role in metabolism and are used to create hormones and other substances in the body. That means everything that happens as a result of regular training is preceded by mitochondrial adaptation on a cellular level.
The right supplements could, theoretically, push those same buttons.
Research on Popular Exercise Mimetic Compounds
Meet ERRs (short for Estrogen Related Receptors).
ERRs are a cluster of nuclear receptors found throughout the body responsible for mitochondrial health and endurance adaptation. But there's no need to worry too much about the technical naming. This simply means that exercise mimetics targeting ERRs will improve the body's ability to generate energy and recover from workouts.
When we exercise our ERRs get "turned on" and trigger the cellular adaptations mentioned above.
Biologically speaking, time ticks away on mitochondrial function. All research concludes that after around age 40, mitochondrial output begins to slowly decline in humans.
Could you trick your body into repairing and growing mitochondria without exercise?
A series of recent studies have zeroed in on just how much endurance exercise mimetics can impact mitochondrial function by directly targeting ERR receptors.
Activating ERRs boosted endurance by 20-30% without any physical activity whatsoever.
If you're wondering what types of diseases and conditions exercise helps protect against, there's a long list.
Studies show exercise has some role to play in treating or preventing up to 26 different diseases including obesity, diabetes, depression, and brain function decline.
If we take even a fraction of the mitochondrial benefits the body derives from exercise and combine them with ERR-activating supplements, the potential for improving quality of life and longevity is enormous.
Who Should Take Exercise Mimetics?
This section is for you…
If you've ever felt guilty for taking a rest day.
If you've never quite made it to the gym but told yourself you would tomorrow.
If you want to stay healthy but dread the inconvenience of exercise.
Exercise is hard. Biology is unfair.
Sprinting your kids to soccer practice four days a week only to come home and hit the weights doesn't come without opportunity costs. There's always more that could be done to improve health.
But that's not the only way to live healthy.
As science continues to unlock what exercise is doing on a cellular level, there is an opportunity to support the body without investing countless hours training.
The keyword there is support.
An oral exercise shouldn't replace a healthy diet and exercise. But if you're already hitting the gym twice a week, imagine what could happen if you tapped into these molecular benefits.
The surface of exercise mimetics is only just being scratched.
Looking forward, the expectation is to see tons of options designed for just about every goal imaginable. But for now, if you want to experience some of the benefits exercise has to offer without investing more hours in the gym…
Exercise mimetics are going to be your new BFF.
Beyond Supplements: Exercise Mimetics + Exercise
Exercise mimetics are NOT intended to replace actual exercise.
One thing to be clear about before wrapping up.
Exercise in almost all its forms is still incredibly valuable to health. The benefits of expanded muscle mass won't come from taking ERR-activating supplements. But mitochondria impact nearly every exercise benefit we can measure.
By taking care of mitochondria with a little cellular science, it's possible to recover fast enough to start logging more gym hours.
The future of fitness isn't limited to the gym.
Use supplements to give the body every opportunity to succeed.
Final Thoughts on Fitness Outside the Gym
Humans were not meant to sit on the couch all day.
There's nothing quite like moving your body and pushing yourself physically.
But what if you couldn't?
What if taking a walk caused debilitating pain?
These new supplements won't SOLVE that problem. But they can help support metabolic health until real-world miles are back on the table.
Here's what to know about fitness beyond the gym:
Cellular exercise mimetics trigger some of the same responses as traditional physical activity
By targeting mitochondria, exercise supplements can improve metabolic health
Many diseases and conditions are improved with regular exercise
Oral exercise mimetics appear to drive many of the same mitochondrial adaptations as training
Supplements are not a replacement for diet and exercise, but can be used to complement training until you can ramp up the real stuff
