Schedules are tight in the morning but you can get a good workout in only ten minutes a day. What maximizes time and works really well is using an exercise routine that splits the body into major muscle groups, exercises one or two muscle groups per day. What really condenses time is doing each exercise slowly about 8 seconds per movement. For instance 8 counts on the lift and 8 counts on the lowering phase of each movement. You need to use enough weight so you can barely perform the last rep. This gives the muscle group enough of a workout to only be done once a week. Can use own body weight, hand weights, ankle weights, cans, or resistance bands.

Lie on you back knees bent, feet on the floor, hands behind your head, elbow pointing outward. In one motion, bring your torso up, elbow pointed toward ceiling. At the same time bring your right leg up to meet it, until your left elbow is about 8 inches from your right knee. Return to starting position: then bring right elbow toward left knee.
Also, before you even get out of bed, there are stretches you can do. Also in the shower or bath a good place to stretch because the warm water helps to warm muscles allowing them to stretch easier. 10-20 reps.
