Abstract: Implementations of squat machines may include a seat coupled to a platform, a first foot brace directly coupled to the platform, a second foot brace directly coupled to the platform, a knee brace post coupled to and extending perpendicularly away from a first surface of the platform, a knee brace arm directly coupled to the knee brace post and extending perpendicularly away from a longest length of the knee brace post, and a knee brace directly coupled to the knee brace arm. The knee brace may be configured to contact the front of either a user's knees or shins while performing a squat exercise. The seat may be configured to temporarily contact a buttocks of a user while performing the squat exercise.
