New here, and I realize this is an old thread, but was excited to see rebounder in the title!

I have a Needak rebounder that I bought close to 20 years ago (Fran McCullough recommended the brand in her Low Carb Cookbook) and it's still going strong. Only have had to replace one spring in all that time.

I've been on/off with it over the years, but for the last 3 months I've been using it for 15 to 40 minutes at least once a day. I just pop in my earbuds, turn on some great music, and pretty much just dance. I always make sure to incorporate plenty of arm exercises with whatever my legs and waist are doing. Great exercise!
