When most people think about trampolines they probably view them more as fun and games instead of something you can workout with. The truth of the matter is that trampolines are great for cardio exercise, building muscles mass and increase bone mass.
My kids got a trampoline for Christmas 2004 and I have to tell you that thing will wear you out. It is amazing how much enegery you use to jump on a trampoline. Above all that you really can feel the muscles contracting in the quads and calves.
Trampolines also come in all different shapes and sizes. There are the mini trampolines that are designed specifically for exercising and there are the larger trampolines which can be used for fun and exercise. Hec, you can also get trampolines for the water!
I personally like trampolines and really enjoy I got for my kids (they really enjoy it too). In fact I enjoy ours so much that I have created a few trampoline review pages on One4Fitness. You can read reviews on the following:
Trampolines - main page for the reviews
Mini trampoline - a little info on mini trampolines
Exercise trampoline - another name for the mini trampoline
Large round and rectangle trampolines - some pretty cool designs here.
Water trampoline - Boy do these things look like fun!
Trampoline accessories - safety nets should be a must. Plus some other cool accessories
All the best,
Gerald
