Electrical stimulation devices are muscle stimulators that use electrical impulses in order to trigger muscular contractions. They are passive workout devices since you don’t purposefully contract the muscles like you would while doing weight bearing or weight lifting exercises. They are touted for their ability to build-up strength and muscle, but the majority of the population dismisses them due to their passive nature. Doctor Nick Delgado used to think that way himself, and was formally a strong believer that you had to go to the gym in order to build strength. However, his opinion changed when he tried the TeslaMax, and now he not only uses it regularly, he also advocates it for anyone who wants to build strength, heal and prevent injuries, and/or optimize their athletic performance.
