Hamstring Curl Calories Burned Formula

Basic mode uses a standard 1.5 ft movement distance and a controlled rep pace:

C = L * R * 0.0029
  • C = calories burned
  • L = machine load in pounds
  • R = total reps
  • 0.0029 = hamstring curl factor for the default settings

Example: 100 lb for 15 reps burns 4.4 calories in basic mode.

What is a Hamstring Curl?

A hamstring curl is a lower-body isolation exercise that trains the back of the thigh by bending the knee against resistance. It is commonly used to build hamstring strength, improve knee flexion power, and add direct posterior-chain work to leg training.
