How much time per week do I have to commit to a workout routine to see results?
This really just depends on how much progress you would like to see. You will be able to have some benefits with as little as 30 minutes a week. But if you are actually wanting to lean down, build muscle mass or just in general see a noticeable difference, then a minimum of 2-3 sessions for at least 30 minutes each would be good. Or if that time is difficult, spread it into multiple 10 minute workouts. The effectiveness of this time will also be determined by how intensely you are working out.
Keep in mind this all depends on what you have time for. Work with what you have available. If you have 2 days where you have an hour to do a killer workout go for it. If you have 20 minutes, 5 days a week available then work with that. You main focus will be working with the time you have and using it as effectively as possible.
For example, if you only have 10 minutes in a day, you could do super sets of pushups, pull ups, squats and jumping jacks. Do as many rounds as you can in the 10 minutes you have, and you will still be doing more than many people do in the gym.
How much you have to work out to see results also really depends on your body type, if you have any health complications and how you are eating. If you are not eating a healthy diet, or eating too much, then it takes a lot more exercise to compensate for that. In fact, getting your eating in order should be the first thing you get in place as long as you are willing to change it, if not then it will take A LOT more exercise.
Do what you can with the time available to you and make it count!
