I have been curious about rebounders of late. They appear to offer a form of cardiovascular conditioning that has less impact on the body than other forms of training, such as running. I continue to search for what I would call recovery workouts, i.e. those I might do on non-strength training days, that get the heart going without wearing the body down too much. Since I have an office job, I need to get some form of exercise almost everyday, but I can't take intense exercise at that frequency. Rebounders look like fun, especially on winter days when you can't get outside to play.
Any thoughts?
