I want to beat my husband!

I want to beat my husband, not into a pulp, but at getting fit. Men of his body type I can tell can shred their bodies so much quicker than most women like me. He was a football playing all american during school and went on to become a aerospace high flying engineer. He's humble about everything and I love him, but a small part of me is so jealous. We both gained around 30 pounds after six years together and now we both have the mind set of wanting a healthier life style. We have installed a gym in our house with an elliptical free weights a bench and I insisted on getting a heavy bag.

Anyone experienced in heavy bag training? I could use some tips. I chose the heavy bag because, I can't literally beat my husband , but I plan on beating him in getting fit. If you can't tell I am very competitive, ha ha.
