Resistance Training, Take 2

The idea of practicing with resistance is not unusual and is generally accepted as a way to build explosiveness and overall strength. When I ran track in high school, we used to do sprints while wearing a belt which had weights attached via rope. Recently, we've begun to incorporate some resistance training into epee practice. So far it's been accomplished as a partner drill. One person does lunges or advance-lunges while their partner keeps a death grip on their back arm, trying to give as much resistance as possible without pulling the front person's arm out of socket. I like the idea of this drill but it is necessarily awkward and also hard on your back arm.

Yesterday, I saw this device for swimmers. I would think something like this would be useful for footwork resistance training, though it may need to offer more resistance than is needed for swimming.

And if any of the Y14s get a little unruly: tether time.
