hey
i did have some problems with that as well i'm a guy, as we got married i got 10-15 pounds after that as well. You know it is kinda you dont have to impress anyone anymore )))) but i was wrong my newlywed wife wasn't pleased )))). i couldnt go to the gym i had a baby and i had to be home, so what i did i started with regular stuff:jumping rope, pushups, pullups and a little bit of abs. i did it everyday for 1 month before it got into my habit (that was the hardest thing to do) , i stopped eating fast food, sodas a,d eating in general after 8 PM. i lost 20 pounds in 2 months.
Then i got into it and found a very good website:
www.mensworkoutguide.com/brad_workout/week1.html
the guy does a lot of stuff there but you can put your workout however you want for your own convenience!
Really good workout
Hope i helped.
