Don't know why I got one way back when, but started using it a few days ago due to some knee rehab. Looking for super low impact cardio.
NASA did a study back in around 1980, looking for an efficient way for astronauts to re-gain bone density after time in space.
There are some outrageous claims, not surprisingly, that others (such as rebounder companies) make, but basically:
- quite easy to do cardio on it with low impact on joints. I will do some lower squats as lower impact plyo to progress beyond my basic slow squat rehab.
- good for your lymp system (the bouncing helps)
- your cells get a millisecond of 0 G at the top of your jump, then maybe 2G at the bottom.
- that is good for your "eccentric strength" (since you're braking). so if that's "internal" for you, probably fantastic for this.
I tried some "zhan zhuang" on it (zhan zhuang while jumping around), and it felt quite fantastic. Good "qi flow" while feeling like my legs can work "springiness" and "eccentric strength" and all that sort of thing. "Internal" upper and "external" lower
