Squat Racks, Power Racks & the Smith engine

The squat rack is a free standing frame which allows a man to load and unload a barbell from an elevated position.

The power cage provides the same but being composes of 4 posts it seat catcher pins which allow the learner to lift safely alone. The catching pins are set a few inches below the lowest position of the lift. In the event of a fail the bar is bailed and dropped onto the catchers.

Some squat racks feature catchers also but are uncommon.

The Smith machine looks similar to the Power Rack but features a bar fixed to vertical rails. It is of utmost point to recognise the difference between the Smith machine and a power rack since each dictates a very dissimilar training style.

The power rack provides:

- A method of Loading
- A method of unloading
- A failsafe.

A Smith machine provides the same but dictates movement pattern and it is this which renders the piece of tool useless to anyone who wishes to train effectively. Since the bar on the Smith machine is guided by vertical rails it does not allow for natural three dimensional movement. This is more of a problem that citizen might assume.

As a learner moves a bar through the range of appeal using free weights their body requires free time of movement to make micro adjustments which include the ways in which joints move and the ways in which muscles contract. This is inclusive of small stabilizer muscles which need free time to establish to do the job they are intended to do; stabilizing the body with or without an external load. This is regarded as functional training since it has possible carryover into the real world.

Restricting the body to work within a two dimensional plane can generate stress upon the joints and programs incorrect motor pattern. "Motor pattern" is a studying process which the body initiates to accomplish a movement more efficiently. As limbs move signals are passed through the peripheral nervous theory to the central nervous theory (through the spine) to the brain. The brain then signals to the limbs through the same path how to convert their accordingly through muscle contraction. It's an unconscious process but it's an vital factor when studying how to accomplish lifts correctly.

A learner who places faith in a Smith machine pushing an external load on vertical rails will riposte to come to be more efficient at interesting in this manner regardless if it has possible detrimental effects to other parts of the organism. An example might be the knees which can suffer due to restrictions in movement and itsybitsy load handled by muscle tissue.

Lifting in the Smith machine teaches how to lift in the Smith machine - nothing more. It has very itsybitsy carryover to the free weight alternative and needless to say is unsuited to any learner - particularly beginners.

These theory also apply to most pieces of tool that dictate a fixed plane of motion. An external load lifted in a real life circumstance will rarely be attached to rails.

Leave the lifting with rails to forklift trucks!
