Consider looking for an exercise program modeled after your husband's military physical fitness regimen so you can easily work out together when he returns. You're obviously not going to exercise at the same level; but, he gets his exercise at work anyway. He'll probably enjoy sometimes accompanying you in an easy (for him) workout just for seeing you improving your physical fitness level. Local places to start searching for info on military styled, in-home beginner programs would be the Activities Director at a base gym and the Community Services office (online you can check out its national website
http://www.usmc-mccs.org/healthpromo...smid=6&ssmid=1 for some
Exercise Program Information). If you can't find anything official at your base, there are unofficial military (branch specific) based exercise programs online including some adjusted for beginners. Perhaps you can get a local recommendation for one of them.
