I'm nearly 65 and have been dealing with a Vestibular (balance) disorder 24/7 for 19 years. bellicon is truly helping with my balance, energy, fitness and overall health. I am able to use this rebounder daily, despite arthritis, Morton's Neuroma on my left foot and a torn meniscus in my right knee! It is low impact and fun! Did I mention I'm a very firm size 4? I only wish I had known about it 20 years ago! Thank you, bellicon!
