I have recently bought a large trampoline for my kids. I love to jump on it with them. Is a steady jumping session say about 30 to 45 min a good calorie burning workout? I do do an everyday workout, but want to bust off my plateau and loose the last 10. I don't use the trampoline every day, Is it worth my while to get on everyday?

It's a surprisingly good workout. I run 4-6 miles most days and still get winded playing on the trampoline with my brother's kids. It's kind of like a slow (and much more fun) jump rope, but you have to use more overall core for balance. If you're looking for variety, go for it. Maybe not as your sole cardio source, but no reason not to do it most of the time. If you have a heart monitor, you might compare your rates on the tramp vs. other cardio methods.
