You wipe your eyes, splash some water on your face, and make your way to the gym, living room, or basement. There isn't much time before having to get ready for work and keeping up with a solid fitness plan. Early morning workouts may require a lot of motivation but offers opportunities to improve cardio strength and generate fat burning metabolism.
Once you get into a routine of working out in the morning everything becomes easier and you are less likely to skip on your practice. Exercise at night must compete with family, t.v. and any other activity. It becomes easy to find excuses why one should not work out at night when there are so many other things to do.
Early risers don't have all of those distractions. As soon as they wake up and finish their coffee they can start their workout. There are less distractions and it gives you a jolt of energy that can last throughout the entire day. Because you have completed your workout you can focus on other stuff.
If you frequent a gym there are less people and more available equipment in the mornings. Most people either go after work or later on in the evening. Those who go in the morning are generally older and more mature. Most of the equipment is still available and in good order.
In addition to the open gym, cardio boost, and early accomplishment of your goals you may be able to get the first breath of sunlight in the morning. If that doesn't provide you with a mental boost in the morning to go along with your physical boost then your a hopeless case. Get up early, get it done, and got on with your day.
