Hi dvokm5,
Thanks for writing and for the information! Jumping on the mini-tramp burns a lot of calories per minute... of course, it is all based upon your height, weight, and the intensity at which you're exercising!
Whatever workout you're performing, always challenge yourself by increasing intensity and/or duration frequently. Again, there are many resources, internet sites and software programs out there that will give you an estimate based upon your personal information and fitness level, how many calories that you're burning for the exercise you're performing!
Best of luck!
Kelli
