"feeling" the results isn't really a good way to evaluate a workout.
When you first start working out, you probably will feel some soreness. But as you continue to work out regularly, your muscles will get better at the recovery process, and you will experience less soreness.
Fatiguing your muscles (ie. the point at which you feel you cannot do another rep with the correct form) is the best measure of workout effectiveness. Ideally, you should reach this point with 12 reps or less (the fewer the better).
