Total Body Workout Routine
The only workout routine you should use is one that is designed specifically for your body type. This is because everyone's body is different and responds differently to training. Finding the right combination of exercises that is going to allow you go build the most muscle is your goal. The first step is figuring out your body type.
If you gain weight easily and put on muscle without much lifting, finding a routine should not be too difficult. You can look in a muscle magazine. These are intended for a wide audience and help people that gain weight easiest. Another good source of advice might be someone at they gym who also gains weight and builds muscle easily.
If you are a hardgainer, you must be much more selective in choosing a workout routine. Hardgainers work out just as hard and as long as everyone else but do not see the same improvements to their body. This is because their muscles recover slowly and they are usually training with tried muscles. To get the muscle gains they want, they need to allow ample time for these muscles to heal.
The best way to let the muscles heal is to find a routine that only calls for a few hours in the weight room each week. The workout sessions should not last longer than 1 hour. This will ensure muscle growth while allowing ample time for the muscles to heal. The best schedule to use is to lift one day and then rest one day. This means you will be lifting 4 days one week than 3 the next.
