Weight training involves use of equipment that enables variable resistance. This resistance can come in form of "free weights" like barbells and dumbbells, machines that use cables or pulleys to help you lift weight and bodyweight exercises like pull-ups or dips.Free Weights vs. Machines vs. Bodyweight Exercises
For maximum muscle gain, focus of your workouts should consist of free weight exercises. Not machines or bodyweight exercises. This is not to say that you should not use machines or bodyweight exercises, but they should not be focus of your training. To get an effective, muscle blasting workout, you must stimulate most muscle fibers as possible, and machines do not do this.
The main reason for this is a lack of stabilizer and synergist muscle development. Stabilizer and synergist muscles are supporting muscles that assist main muscle in performing a complex lift. The more stabilizers and synergists worked, more muscle fibers stimulated. Multi-jointed free weight exercises like bench press, require many stabilizer and synergistic muscle assistance to complete lift. On other hand doing a bench press using a machine will need almost no stabilizer assistance.
Since machines are locked into a specific range of motion and help to support weight along that path, they fail to stimulate muscles that surround area you are working (stabilizers). This is a mistake. If your stabilizer muscles are weak, then major muscle group will never grow!
Free weight exercises like dumbbell press or squat, for example, put a very large amount of stress on supporting muscle groups. That's why you will get fatigued faster and not be able to lift as much weight as you did on machine. But you will gain more muscle, become stronger very quickly and have a true gauge of your strength.
If you use machines in your program, they should be used to work isolated areas and only after all multi-jointed exercises have been completed.
Beginners should begin with a limited combination of machine exercises, bodyweight exercises and mult-jointed free weight exercises. Before increasing weight levels, they should work on becoming familiar with proper form and execution of each. Soon, bodyweight exercises will become insufficient to stimulate growth and they will need to focus on more free weight exercises.
Multi-Jointed Exercises
The exercises that work large muscle groups are called compound (or multi-joint) movements that involve simultaneous stimuation of many muscle groups. These compound exercises should be foundation of any weight training program because they stimulate most amount of muscle in least amount of time.
Here are basic movements:
* Bench Presses (works chest, shoulders, tricep)
