There are some simple things to keep in mind once you begin your weight training regimen.
First, you need to decide if you're going to join a gym to work out, or if you are going to invest that same money into your own personal gym.
If you decide to purchase your own gym, then you need to figure out what equipment you will need, how much you will need, and how you're going to store it in your home.
As soon as you get those things sorted out, you can begin your weekly routine.
Remember that you cannot lift weights every single day of the week.
You shouldn't even lift weights on consecutive days.
It is best for your body if you don't push yourself too hard, because if you don't give your body a chance to rest between work-outs, you could risk injuring yourself and not maximizing the hours you work.
Having said that, you need to push your body harder than you normally would in order to increase your strength and endurance.
You should only be able to lift as much weight for the number of reps you want to do.
That is, if you want to do five reps, you should not choose a weight level when you can easily do double or triple that.
The other two basics are repetition and specificity.
You have to continue the same reps in the same order several times.
One rep on a machine or with a free weight will not be enough to strengthen your muscles.
You should also target specific muscle groups.
Weight should work on your quads, your biceps, your back, etc etc.
