Where you should feel it, the one cue to remember, and quick fixes when you feel it somewhere else.

You should feel it inBack thighs

Back of the thighs, strongest near the knee.

Key cue (the coach says it during the set)“Hips down, curl the heels to the glutes, lower slowly.”

Tempo · Curl 1 s · squeeze 1 · lower 3 s

Choosing the load: Pick a weight you finish with 1–2 good reps left. 4+ left = too light; form breaks = too heavy.

Feel it in Lower backHips lifting off the pad. Go lighter and press the hips down.
Feel it in CalvesPointing the toes and using the calves. Pull the toes toward your shins.
Barely felt itToo light or too fast. Lower for 3 seconds, pause 1 second at the stretch, and pick a load that leaves only 1–2 reps in the tank.
Joint painSharp or joint pain is a stop sign: end this set, lower the weight, shorten the range — if it repeats, switch to an easier variation.

During a workout we ask after the first set where you felt it and give the fix right away — and remember it for next time.

Sit tall with your back supported so the target muscle does the work.
Fix your eyes on a point in front of you to help with balance.
Leaning your torso slightly forward increases the hamstring stretch.
Seated curls train the hamstrings at longer lengths — a great choice for muscle growth.
Adjust the seat so your joint lines up with the machine’s pivot point.
