The key to creating daily workout schedules is being realist in what you actually can and will accomplish. If you sit down and right out workout routines schedules that have you doing 3 hours of running every morning before dawn you might be setting yourself up for failure. If you are extremely busy you probably need to be looking for a free workout program that is around 30 minutes or so a day. Even if you have lots of free time about an hour a day is really all it takes to build a great body, improve your strength and lower your body fat.
Typical daily workout schedules involve a mixture of cardio conditioning and weight training in order to get a well rounded workout throughout the week. You can probably imagine all kinds of unique daily workout schedules but the most common involve weight training 2,3,4, or 5 days a week. Then you do the cardio either immediately following the lifting or on off days.
Now all you would do is focus your weight training style to align with your most important goal. So if you subscribe to the philosophy of this site and focus on strength training it would most likely involve low reps and heavy weights. If you disagree and believe in a bodybuilding style or toning method of training then you might have some interval style weight circuits or some high rep isolation exercises (wasting your time).
If you had a goal of weight loss your daily workout schedules might just have cardio and could be something as simple as run every day to lose weight. If weight doesn't come down then run longer. Of course you could spend all your free time running and it not mean a thing if your diet is loaded with junk.
If you had a goal of building muscle then you might have a strength training program as your workout routine that makes up your daily schedule.
The point is that your workout schedule has to be one that works for you and aligns with your goals. If I said run 5 miles a day and bench press 3 times a week but you hated running and had no desire to have a big bench press then it would be an awful program that produce no results that you cared about. On the other hand if all you cared about was how large your bench press was then you would jump right on board and call this the perfect program.
In reality very few people need to have daily workout schedules and most can get away with training 2-3 times a week. In powerlifting and strength training rest is more important than time spent in the gym. Most strength athletes train just a couple hours a week and then spend the rest of their time resting and eating. Endurance athletes are known to train long hours but even they don't train every day. I would say the only exception would be if you are into a sport, then you might consider adding in some skill training to your workout program so that you had a balance of sports specific training, strength and conditioning.
If you are a hardcore athlete (like you are going to make your living doing it) then you might even through in an a.m. and p.m. session so you could do something like skills drills in the mornings and one of the other fitness aspects in the evening. Twice a day sessions are also a good way to up the calorie burn if you are looking to drop a lot of weight quickly. You could do some light cardio for time in the mornings and then focus on high intensity training or weight lifting in the evenings.
The options are pretty much limitless but not really that difficult to put together a workout program with a daily routine you can live with. Just keep your most important goals in mind and lay out daily workout schedules that makes since. Stick with what you can realistically do and it will be fine.
