The Model

The stickman displays the body part lengths selected above with the sliders, bar path in blue and the current selected squat position. The squat position is based on the ankle, knee and hips breaking at the same time while the models center of gravity (CoG) is maintained over mid-foot.

The knee flexes linearly while the ankle flexes quicker in the beginning of the squat. 'Linear' meaning that when the model position is 25% of the way from standing to squatting, the knee has flexed 25% from the standing angle to max. When at the half way position the angle has gone through 50% of its max angle. Finally at max angle when the model is fully squatting. Breaking in a linear fashion may not be correct for the knee, nor the ankle flexing faster early in the movement. Just remember it's a model and won't show exactly how you squat.

CoG calculations take into account the bar mass, each body segments mass and each segments own CoG. This can cause the bar to travel forward past mid-foot to maintain the total models CoG over mid-foot. As a result the bar does not always travel in a vertical path.

Stance

Use the stance slider to change the angle of your feet e.g. feet pointing straight ahead equals 0 degrees and straight out equals 90 degrees.

Those of you with long legs will benefit from a slightly wider stance and feet angled out. This will make your torso more upright and bring your hips in closer to midfoot.
