How to do it

Set up

Adjust the seat so the knees align with the machine pivot.
Secure the thigh pad and place the lower pad above the heels.

Do the rep

Curl the lower legs down by bending both knees.
Return the pad under control until the legs reach the start position.

What counts as a rep

A rep counts when the pad reaches the seat-set curl stop and returns to the seat-set start stop.

One rep starts with the pad at the seat-set start stop, curls until the pad reaches the seat-set curl stop, and ends after a controlled return to the start stop.

Breathing

Exhale as the knees bend; inhale as the pad returns.

Cues

Keep the thighs under the pad.
Move both legs together.
Control the return.

Common mistakes

Hips lift
What you seeThe hips move away from the seat as the knees bend.
FixUse less load and keep the thighs secured.
Supported hips keep the movement at the knees.
Weight returns quickly
What you seeThe pad pulls the legs back to the start.
FixReduce the load and control the full return.
A controlled return maintains tension and prevents the stack from slamming.

Stop the set if

Stop if you feel sharp pain.
Stop if the hips lift or the pad returns without control.
End the set when you cannot meet the stated range under control.

How this page was checked

Draft. A coach reviewer has not signed this off yet.

Technique, cues, rep standards, breathing, stop cues, and error corrections are original draft text. Independent technique sources and coach review remain required.
Anatomy, classification, and equipment use unapproved blueprint planning hints. The assigned review tier must confirm them.
Allowed metrics, side counting, and environment values are draft interpretations of the planning metadata.
This pass treats load-and-reps as the legal modes supported by the CSV logging model; reviewer approval remains required.
The rewritten summary, rep standard, breathing, stop cues, and common errors are editorial judgements pending the assigned review tier.
Legacy relations are movement-pattern and equipment judgements; engine edges remain empty pending S2-CAT-005 approval.
Pass 2 rewrites the finish standard as a counting-only criterion and replaces the web title, summary, and meta description with exercise-specific copy; these editorial choices require review.
Pass 2 defines a visible movement endpoint where the earlier draft relied on a vague range or control phrase; the endpoint requires coach review.

All instruction and editorial text in this record is original draft copy written for Allena. Planning metadata comes from the internal Wave-1 blueprint and exercise brief.
