Does Electric Muscle Stimulation (EMS) Hurt?

What Does EMS feel like?
In short… at low levels, EMS feels like light vibrations against your body, similar to one of those electrical massagers that you may have in the back of your cupboard at home. At higher levels, it feels as if your muscles are contracting on without you telling them to. At extremely high levels and in the hands of someone untrained EMS does have the potential to be
uncomfortable.

So it doesn't hurt, but is it safe?

Yes. It most certainly is safe. In fact, a large amount of research has been done into the safety and efficacy of electric muscle stimulation in rehabilitation and performance settings.
EMS has been around for centuries in the rehabilitation space, it was deemed a long time ago as a safe tool to activate muscles when someone could no longer do this effectively on their own. Such as after surgery, injury, or even in those who have lost the use of 1 or more limbs.

As we get older the strain that exercises such as lifting weights, running, HIIT, etc can cause often lead to a lot of pain and discomfort in our joints or lead to injury if our existing muscles are not strong enough. EMS allows us to strengthen muscles without the impact on the joints and bones that is unavoidable with most strengthening exercises.
