I am going to ask you a different question?
Do you like what you're doing? Because that makes the difference. I get bored easily and I can't imagine keeping a pace of 1.5 hours a day forever plus with all that you could overtrain.
Personally I break things up and do things that I love and add different things. I walk, I bike, I will add back in strength training eventually, and of course there is always Yoga. I shoot for about 5-6 hours a week of exercise with lots of flexibility and options.
Remember we want to lose weight, but its a journey, slow down and figure how to make a change that will stick and you will enjoy rather than the flash in the pan thing for the next 5 min. (Plus have some fun! I am thinking about signing up for dance again
