When it comes to strength training, the degree of challenge is what is important, not the duration.
You should be aiming to fatigue your muscles in 12 reps or less. Once you can get in 12 reps in a set, it is time to move to a heavier weight/more challenging exercise.
By choosing compound exercises that work several different muscles simultaneously, you can get in a workout in just a few moves.
For example, 2-3 sets of squats, and 2-3 sets of deadlifts, and you are pretty much done with your lower body in 5-10 minutes.
Planks for the core. Pushups (modified, wall or incline pushups if necessary) and pull-ups/lat pull downs/bent over dumbbell rows for the upper body, and that is pretty much a full body workout.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
