2-3 hours a day x 5 days a week -- 10-15 hrs -- is a huge amount of time to spend on weights.

A Starting Strength routine shouldn't take more than 3-4 hours a week, and you'd be moving way more than your bodyweight.

Or, if you can find room in your dwelling for a barbell and plates, Pavel's Power to the People program would take a total of 2-3 hours a week. Again, you'd be developing strength, rather than endurance.

Having said that, if you've found something you're happy with, cool. The routine you actually do beats a theoretically superior routine you don't get around to.

A big part of gym time is getting there, changing (twice) and taking a shower. When I used to go to the gym, I did SS and it took between 50 and 60 minutes to complete the workout, but I left home at 5:30 AM and got to school at 8:00 AM. There was one hour to walk to/from the gym and about 30 minutes to change and wash up.

Since I started working out at home (same kind of deal as OP), I got less strong, but not by much, but I also have more time.

Given your situation, I'd recommend investing in some kettlebells and elastic bands (get the latter from a powerlifting specialist, they'll be cheaper and better).
