Enter the total weight on the machine (lbs) and the angle of the leg press (degrees) into the Calculator. The calculator will evaluate the Leg Press Weight. 

Leg Press Weight Formula

The following two example problems outline the steps and information needed to calculate the Leg Press Weight.

LPW = MW * SIN (A)

Variables:

  • LPW is the Leg Press Weight (lbs)
  • MW is the total weight on the machine (lbs) 
  • A is the angle of the leg press (degrees) 

To calculate Leg Press Weight, multiply the weight on the machine by the angle of the machine with the ground.

How to Calculate Leg Press Weight?

The following steps outline how to calculate the Leg Press Weight.


  1. First, determine the total weight on the machine (lbs). 
  2. Next, determine the angle of the leg press (degrees). 
  3. Next, gather the formula from above = LPW = MW * SIN (A).
  4. Finally, calculate the Leg Press Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total weight on the machine (lbs) = 300

angle of the leg press (degrees) = 20

LPW = MW * SIN (A) = ?
