Sure. I'm in the military and get 5 hours of unit PT per week. I work out for an hour each lunch for 5 more hours. I'm lucky in that we have gyms at work. For the last 4-7 hours I train an hour a day, when possible, in Brazillian Ju Jitsu and Muay Thai. Unless you're quite fit I wouldn't recommend 14+ hours per week. I've been in the Army for a decade and my resting heart rate sits at about 40 BPM. Athlete levels of training takes years of buildup and is likely to be harmful to someone coming from a sedentary lifestyle. I'm a very active person in all aspects of my life. I don't sit still, I can't even sit still long enough to watch a tv show. Even my workaholic Commanding Officer tells me I need to slow down. The biggest challenge is sleep. For 3 hours of training you really need to make sure you get 8 hours. How old are your children? Once they reach a certain age you can incorporate them into an active lifestyle. For example, once they're 3-4+ you can take them out for a scooter while you walk. If they're younger you can put them in a pram and walk. Regular walking is a really underrated exercise for people battling a sedentary lifestyle. When I'm injured I increase my walking to offset lack of exercise. I'm a single father and the way I incorporate my children into a busy life is to make it part of their life. Cooking healthy dinners take a lot of time, so I have my kids in my kitchen learning about cooking so I multitask cooking and quality time. Finally I should mention I'm quite introverted. I have plenty of friends but I don't choose to socialise often. I also don't have a commute worth mentioning due to living next to base. I know a lot of others have 2 hours per day of commuting and this could be the difference between how I find time to train.
