The vast majority of those that don’t work out as much as they should cite lack of time as their main reason. The assumption is that if you don’t spend hours in the gym every day you won’t see results. But that is not the case at all. What it comes down to is how focused you are and having a clear game plan before going in to your workout.
You may need to take a few lengthier visits to the gym to learn where everything is located, but once you are comfortable in your surroundings, you can easily get a full body workout in an hour. Since your working your entire body, it is important to remember to do give your body a full days rest after the workout. Ideally, you could do this 3 or 4 times a week.
Start with fifteen to twenty minutes of cardio. The first few minutes should be for you to warm up and get your heart rate in your target area. Once you are warmed up, push yourself by running faster with a higher incline on your treadmill or increasing the resistance on other cardio machines. As soon as you are done with your cardio, go immediately to your first gym machine.
Using gym machines is very convenient, but you could also use dumbbells and other weights instead. Choose ten machines that cover a wide variety of muscle groups. Keeping your heart rate in its target area will help burn more calories and build muscles faster, so with each machine, do two minutes of repetitions without stopping. Take a minute to get to your next machine and repeat. For a run down on all of the many gym machine options you could use, go to the Gym Machines Intro Guide.
If you keep to schedule of two minutes of workout and one minute to get to the next machine, you will have used a half an hour. Use your last time left in the hour by hopping on a different cardio machine than you used earlier and after going at a rapid pace, use the last few minutes to cool down.
At the end of the hour, you will have burnt several hundred calories and have sufficiently worked every muscle group. All it takes is three hours a week of pushing yourself to the limit. I know you have three hours, so get out there and give it a shot!
