Yes Jumping on a trampoline is not only fun but it's great exercise and can help you lose weight as well.
Jumping on a trampoline everyday for 30 minutes per day burns at least 500 calories per day if not more and your health improves as well.
The jumping on the trampoline also gets your blood flowing and improves your heart health because it's a good cardio workout.
If you want to keep your weight off then continuing to jump on the trampoline everyday or at least a few times per week for at least 30 minutes per day can burn off the calories and keep the weight down.
You can also burn belly fat by jumping on a trampoline and the more you jump the more weight and belly fat you lose when jumping on a trampoline.
I jump on my outdoor trampoline daily when I can in the spring and summer and I have a smaller indoor trampoline that I jump on during the winter or bad weather when watching TV.
