Pattern
Knee flexion squat
Setup
- 01Stand with feet hip width apart, near a post or upright to hold if needed.
- 02Rise onto the balls of the feet or keep heels light.
- 03Squeeze the glutes so the hips stay extended.
- 04Brace the trunk so the body moves as one rigid line.
Execution
- 01Bend the knees and let them travel forward while leaning the torso back.
- 02Keep the hips extended so shoulders, hips, and knees form one line.
- 03Lower as far as knee comfort and control allow.
- 04Drive the balls of the feet into the floor to return to standing.
Checkpoints
- -Hips stay locked out; no sitting back into a normal squat.
- -Torso and thighs stay in one straight line throughout.
- -Knees track straight over the toes.
- -The descent is slow and tension never leaves the quads.
Common mistakes
- -Breaking at the hips and turning it into a partial squat.
- -Dropping too deep too soon and straining the knees.
- -Losing balance backward instead of using light hand support.
- -Rushing the eccentric.
Programming notes
- -Use 2 to 3 sets of 6 to 12 controlled reps at the end of a leg session.
- -Build range gradually over weeks; depth is the progression before load.
- -Hold a plate at the chest or move to the weighted version once bodyweight is easy.
