There are a lot of people who have such busy schedules that finding more than 30 minutes to dedicate to a workout is just impossible.
If you talk to almost anyone who goes to the gym to workout and ask them how long a good workout usually takes, they will often answer with; it takes a good hour to get in a good workout, or even; if I don't spend 1 to 2 hours in the gym, I just don't get enough from my workout.
Based on these kinds of typical responses, you can imagine how surprised many of these same people appear to be when I tell them that I only workout for 30 minutes a day, yet still get the kind of results that they do! Many of them will say, no way you only workout for 30 minutes a day!
The plain fact is there are a lot of people who have such busy schedules that finding more than 30 minutes to dedicate to a workout is just impossible. It's not that they don't want to do it; there just aren't enough hours in the day to be in the gym for 1 to 2 hours at a time.
If there was a way to get an effective workout in 30 minutes however, then perhaps they could spend half of their lunch hour in the gym, and the other half eating their lunch. Is it really possible to do a workout in 30 minutes that will bring real results? Yes!
Do spit body part routines, this way you only have half of your body parts to work on each day cutting down significantly on time spent in the gym.
To start with, make sure you have a plan for each day. Write down all of the exercises you will be doing for that day and write down all of the weights you will be using for each exercise. Write down how many sets you will be doing for each exercise and how many repetitions you will be doing during each set. For a few tips, read more here => Quick But Effective Exercises
Upon arriving at the gym, set up as many things as you can in advance so that when you get started, you can keep moving from one exercise to the other without wasting time getting the next piece of equipment set up. This way, you can go strait through each exercise without stopping, take 1-2 minutes rest, and then simply repeat until you finish all of your sets.
On days you are not doing weight training, you can spend 30 minutes on the treadmill or on the stair climber. Combining the two only means you will have to spend more time in the gym and time spent in the gym is what you are trying to cut down on.
While being friendly is ok, don't let yourself get distracted by having a conversation with others in the gym. Explain to people wishing to talk to you that you are on limited time and you just can't stop what you are doing at the moment or better yet, put on a pair of headphones before you begin your workout; they'll get the clue.
In summary, just remember to write out a plan for each day, split those body parts on different days, keep moving during your routine, don't socialize, and don't do weights and cardio on the same day and you will see excellent results in only 30 minutes a day.
