Give the hanging-band 90/90 split squat a try. This advanced variation ramps up stabilizer activity from the core down—so check your ego at the door and avoid going too heavy!

The key to performing this movement correctly is to lower your back knee straight down, rather than driving the front knee forward. Descend until the back knee is just shy of the floor, pause briefly at the bottom, then return to the starting position under control. At the lowest point, both knees should form 90-degree angles—hence the name.

The 90/90 split squat significantly increases activation of the glutes and adductors, and adding hanging-band resistance amplifies the demand on your stabilizers, particularly through the core and lower body.

Fair warning: This exercise is more challenging than it looks! Stick with it, and when you return to conventional split squats, you’ll likely notice a substantial improvement in both stability and strength.
