Just starting, and so far the SanFran workouts are the only ones that fit my needs.
I am 63 yrs old, and while I was quite active at the gym, the balance aspect of the rebounder feels like it will take some getting used to. Reminds me of getting used to the movement of the elliptical.
While it is of course possible to simply do as much as you can, I agree with @barbackman - emotionally and psychologically that doesn't feel so good.
I got this membership with the Costco deal - JumpSport 550fi, and like others who posted a year or two ago, I'm surprised there are not more videos available for such an expensive item. This exercise particularly appeals to seniors - offer us more videos at our level, please!
