I need something fitness wise for the upcoming winter months, so I decided to go with a mini trampoline -
Walmart has the Gold's Gym Circuit Trainer 36" Mini Trampoline w/resist bands. on sale for 34.77.

[Gold's Gym Circuit Trainer Mini Trampoline also includes:
2 resistance cords for upper body workout
Electronic monitor that measures time, calories, and number of jumps
Mini-trampoline stands on 6-legs.
Gold's Gym circuit trainer workout DVD ]

Easy to move indoors or outside, no motor/or belt like a treadmill, I had one years ago.

I read that trampolines are very good for lymph flow, bone strength & overall conditioning. Just a very mild bounce movement stimulates the lymph system, you don't even have to get airborne.

The store near me didn't have it on the shelf so not sure when it will arrive in the store for pick up.
