Regular exercise, including cardiovascular and strength training, can help improve stamina and endurance.
Pelvic floor exercises have also been found to increase sexual stamina in men affected by premature ejaculation.
In addition to exercise, making lifestyle changes such as eating a healthy diet and reducing stress can also help improve stamina.
It is important to note that reduced stamina that isn’t improving may be caused by an underlying medical condition.
Even better, men can also train for bigger loads and multiple orgasms, and that’s pretty easy to learn too!
