During your weight training some muscle pain can be expected, and you would be astonished just how easily it is to forget simple things such as proper warm ups and  proper use of certain machines.
Proper Warm Up
It is very important for you to warm up before you work out. Even though you may not see the benefits to a quick five minute cardio period before your workout, your heart will give thanks to you.
Your pre workout warm up could be in the form of a quick cardio session on the stair master, or some light jogging. You can also start off with very light sets, in such way you will warm up your muscles and joints for the further big lifts. Owing to a working one or two light sets before you begin your workout, you will prepare your muscles to the further movement and reduce your chances of injury.
Many bodybuilders are consistent with a certain intensity principle known as “Pyramiding”. This principle means that they begin their workouts with lighter weights and higher reps, and little by little move to heavier weights and lower reps.
During the Workout
During the workout, make sure that you are going to use heavy weights which you can handle. It is in your interest, because it will help you to keep proper form for the entire range of movement. If you try to use heavier weights with bad form, you will not get much out of the workout. Also, if you lift slightly lighter weights, by thrusting the barbell up and down at lighting speed, this will not only give you any results, but also increase your chances of injury.
Breathing
A temporary increase in blood pressure and may be caused by lifting weights. And when you hold your breath, it is a sure way to make it increase even more during exercise. There are some arguments over whether or not you should exhale on the exertion or not. But you have to remember the most important thing: keep your breath controlled.
It doesn’t matter either breathe out on the exertion, or breathe in. But you have to maintain that speed throughout your exercise. Uncontrolled breathing can cause many people to get nauseous or even throw up during intense training. You can even lose your consciousness, depending on the circumstances, and of course, if you have a heart condition, make an appointment with your doctor before you begin incorporating bodybuilding or any other form of exercise into your life.
