Working out with tracking your results is only half the picture. Let me paint a picture, what would happen if the Red Eye to London didnt check its course on the way out of JFK. Even if for just one hour the pilots didnt keep an eye on thier course they could veer hundreds of miles off course. Even if they then realised the route the were taking wasnt the right or optium way they may have wasted that hour of flying. By keeping an eye on thier course they deliver safely to your destination and on time.
The same is true of workout tracking. If you track you results you are going to know what works for your body and if you are getting gains or losing inches. If you did the same exercise at the same wieght for 3 months you might get ok results but compare this to someone else who added some variations to target the same muscle group and identified when they could increase the weight. The differences would be dramatic.
So where to from here. First of all you need to get a base. To get this break you body up into its major muscles groups and perform a one rep max to find out your starting weight. Also take measurements of the same muscle groups. Now that you have a base in 3 months when you re-test your going to know exactly how far you have come. During this time whether you train once, twice or even three times a week write down the exercises, repetitions and also the weight you are lifting. This way its much easier to remember what you did last week and your more likley to push yourself to that next weight.
The best tip I can give is that If you plan on being the best then you need to train like the best. Never under estimate the workload of your peers. The greats of the game (even with all of the skill that they possess) are first in the gym and last to leave. Use this mentality when you set out to train. Put in 110% and thats what you will get back from yourself.
