Prepare your excercise routine in such manner that instead of working out entire body everyday you spilt your body-parts and perform them individually or in pair.For example you can pair your 'arms with back','chest with shoulder','legs with abdomen' etc.

2)Pyramid Training :- During your training session start with light weights with higher reps (15 to 20) and then in every next set increase the weight gradually and decrease the reps(5 to 8).

3)Rules Of Muscle Priority :- Hit your weakest body part first during your excercide routine when you can train it with more more intensity because your energy level is higher.For eg. if your arms are weak then train your arms first during your 'arms-back' routine day.

4)Progressive Overload Principles :- Under this basic rule it is stressed that you increase your Excercise Intensity in a progressive manner over a period of time and allow your muscles work harder next session. It can be increased by lifting more weights than the last session or by doing more reps or sets or by decreasing your rest period between sets.

5) Rules of continuous tension: Donot rest at the top or bottom of the movement of an excercise.Control both the up and down movements so that the entire range of motion is smooth and continuous process maintaining a constant tension in the muscles.

6) Rules of muscles confusion :- Intermediate to advanced bodybuilders should constantly keep confusing body muscles by changing the excersise variables i.e. order of excercises , no. of sets, no. of reps, length of rest periods etc.

7) Isolation training rules :- It is an advanced technique to single out an individual muscle and force it to grow. Preacher curl for biceps, press down for triceps etc. are examples of isolation training.

8) Compound sets :- Perform two different excercises of same muscles group back to back without any rest in between. For example shoulder press with dumbbells followed by front raise.

9) Super sets :- It is just opposite of compound set technique. Perform two different excercises of the two different muscle group back to back without any rest in between. For example biceps curl followed by triceps extension.

10) Principles of forced rep :- At the end of your each set let your training partner or a spotter help you do few more reps and force you to go beyond muscular failure. The training partner should apply only enough force to help you overcome the sticking point.

11) Pre-exhaustion Principles :- This principles applies to advanced body builders to overcome the stagnation. In this technique of excercise you first pre-exhaust a muscle with a specific excercise and then move to multijoint excercise involving that muscle.For example you dips for your chest and then move on to bench press. Another example is you do Leg-extension first and then move on to squat.

12) Rest pause principles :- This principle is just opposite to continuous tension in as much that in this you take brief rest during the set and squeeze few more reps and again take a brief rest of about 30 to 40 seconds and do another few reps. However you should apply this principle only when you are working out with your training partner.

13) Principles of negative rep :- Under this rule while positive part (lifting part) is helped by a spotter because you cannot lift any more rep, the negative part (lowering weights) is performed by yourself without help.

14) Drop sets :- In this set, after performing maximum No. of reps, about 15% of weights are reduced and immediately few more reps are performed. Again about 15% of weights are reduced and immediately few more reps are performed without help.
