Steps
- Adjust the machine lever to fit your height and sit on the machine with your back against the back support pad.
- Place the back of lower leg on top of padded lever (just a few inches under the calves) and secure the lap pad against your thighs, just above the knees. Then grasp the side handles on the machine as you point your toes straight (or you can also use any of the other two stances) and ensure that the legs are fully straight right in front of you. This will be your starting position.
- As you exhale, pull the machine lever as far as possible to the back of your thighs by flexing at the knees. Keep your torso stationary at all times. Hold the contracted position for a second.
- Slowly return to the starting position as you breathe in.
- Repeat for the recommended amount of repetitions.
Tracking it in OneRep
Add the seated leg curl to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.
Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.
Where the instructions come from
The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
