Split squats improve single leg strength, stability and coordination. Its important to train single leg patterns because many of our daily activities are performed on one leg – walking, running, etc.
Begin in a staggered stance – one foot in front, one foot back. Brace your core and slowly lower yourself straight down, dropping your back knee to the ground. Once your knee is within a few inches of the ground reverse the motion and return the the start position.
Avoid letting your front knee cave in. Maintain a stable foot, keeping your knee in line with your toes. Dropping straight down will also prevent your front knee from traveling too far forward over your toes.
Your back knee should be slightly behind your hip as you perform each rep. Keep an appropriate distance between your feet throughout.
