Exercise in a pill

Summary

Researchers aim to create exercise-mimicking drugs to benefit those with frailty or chronic illness. While challenging, progress is being made in identifying and regulating exercise-related molecular signals. Some experimental drugs have shown promising results in animal studies and early human trials.

Key Takeaways

1. By deciphering how movement benefits the body, researchers hope to develop medicines that can offer some of the same perks—without the workout.
2. More than 90% of treatments that enter human studies fail.
3. Scientists have already identified many important exercise-related signals and have even developed compounds to regulate them.
