Not effective. As you say, every minute of the day counts, so pick the training methods that are most effective, ie. gives the most result per minute spent. For cardio, do intervalls.
4 high intensity running periods that last for 4 minutes each, with 2 minute breaks between each one. Do that 3 or 4 times a week and you'll have great cardio in no time at all.
For strength, without going into too much detail - the fastest way to become stronger is by doing few, but very heavy reps, while if you want to build muscle mass you need more reps. So you should do a combination of the two - have some sets of few, very heavy reps, and some sets of more, easier reps.
Good luck
