Place your shoelaces on a bench or flat surface that's at or below knee height. Have your active leg a large step away, a further step is more glute focussed whilst closer is more quads.

Start by bending the front knee to lower the body down until the front leg makes approximately a 90 degree bend. Then push through the front heel and return to the start position. Activate your core to keep a straight back throughout. Your back foot should be used for balance and have minimal weight pushing through it. Repeat for the desired repetitions then switch sides.

Avoid allowing the front knee to cave too far inwards.
