Proven Science

The Private Gym is supported by decades of research

The Science is simple. Work out a muscle and it gets stronger. Stronger pelvic muscles create harder and longer-lasting erections.

In 2005, the British Journal of Urology International published the most comprehensive study ever conducted on the effects of pelvic muscle exercises on men. The results were overwhelming, 76% of the men significantly improved their erectile function.

Strengthening the Pelvic muscles results in:

  • Stronger erections
  • Improved sexual stamina
  • More intense and stronger ejaculations
  • Reduction and prevention of incontinence
  • Reduction or prevention of prostate inflammation
  • Increased circulation of blood to the penis

Decades of research


The Private Gym exercise program builds upon the scientific findings of Dr. Arnold Kegel, who, in the 1940s, developed simple exercises to prepare women for childbirth. For decades, doctors and leading medical institutions have recommended these exercises for women.

Dr. Kegel also discovered that these same exercises also improved sexual function. In fact, Dr. Kegel’s work led to the development of the many female pelvic muscle exercise devices that are currently on the market today.

Thanks to the Private Gym, there is now a simple and safe way for men to strength their pelvic muscles.
