Identify the seated machine
This guide concerns a seated leg press with a backrest and a footplate ahead of you. Ask gym staff to demonstrate the seat adjustment, loading and start and finish controls for that model. An inclined sled has different controls. The machines and free weights guide helps compare equipment without treating displayed loads as interchangeable.
Fit the seat and feet
Begin with little resistance. Adjust the seat so your back and head remain supported and your feet sit securely on the plate around shoulder width apart. The NASM technique guide describes an initial knee bend near a right angle. Use a comfortable setting rather than forcing a deeper position. If the machine cannot fit you, choose another option with a trainer.
Press without locking the knees
Hold the intended handles and push smoothly through both planted feet. Let the knees follow the direction of the feet and stop before forcefully locking them straight. The Mayo Clinic demonstration describes these contact and control cues. Keep the pelvis against the seat instead of lifting it to move more weight.
Return before losing contact
Bend the knees slowly toward your starting position. Do not let the weight drop or chase extra depth by rounding your back or lifting your heels. Shorten the movement or reduce resistance if contact changes. Stop for pain, dizziness or lost control. Recent injury, surgery or an exercise restriction calls for individual advice.
Record this machine and setup
Note the model, seat setting, displayed load and controlled repetitions. Another machine needs its own record. The goblet squat guide describes a separate standing option. Use the progression guide only after a repeatable comfortable setup. Explore gym planning with Fitonomy; an app cannot assess your form. No particular load or repetition count is required for this practice.
A leg press and a leg curl use different motions. Before trying knee flexion, review the seated leg curl setup and check the knee pivot and calf roller.
A leg press uses a footplate rather than a front shin roller. For the distinct knee straightening machine, check the seat and pad fit for leg extensions instead of carrying over your press settings.
