IPL'S LETS GET FIT~LEVERS

[IronpumpedLady]

TweetFor your arm, leg or any body part to move the appropriate muscles and bones must work together as a series of levers. A lever comprises of three components -

Fulcrum or pivot - the point about which the lever rotates
Load - the force applied by the lever system
Effort - the force applied by the user of the lever system
The way in which a lever will operate is dependent on the type of lever.

Classification of Levers

Class 1 - The fulcrum lies between the effort and the load
Class 2 - The fulcrum is at one end, the effort at the other end and the load lies between the effort and the fulcrum
Class 3 - The fulcrum is at one end, the load at the other end and the effort lies between the load and the fulcrum

Class 3 is the most common class of lever to be found in the human body.

Examples in strength training

Class 1 - Seated dumbbell triceps extension
Class 2 - Standing heel lift
Class 3 - Seated biceps curl



STAY STRONG~~!!!
