How Iridium Programs This

Iridium categorizes this exercise as a stability-focused accessory lift that contributes directly to your glute and quadriceps volume benchmarks. To prevent overuse, the AI analyzes your 7-day workout history and utilizes this rotational variation when your standard sagittal-plane movers usually targeted by squats require recovery. Progressive overload is managed by tracking RPE and weight trends specific to this movement, ensuring intensity scales relative to the balance demands of the medicine ball.

Form Cues

Keep your hips squared forward throughout the movement
Hold the medicine ball close to your chest with elbows tucked
Step your back leg diagonally behind your front leg
Drive through the front heel to return to standing
Keep your front knee aligned over your second toe

Don't

Don't let your hips rotate toward the back leg
Don't allow your front knee to collapse inward
Don't round your upper back while holding the ball
Don't slam your back knee into the floor
Don't lift your front heel off the ground

Common Mistakes

Rotating the pelvis instead of keeping it square
Stepping too far sideways causing loss of balance
Leaning too far forward at the waist
Allowing the front knee to cave in (valgus collapse)
Holding the medicine ball too far from the body

Muscles Worked

This exercise primarily targets the quadriceps and glutes, with a specific emphasis on the gluteus medius and minimus due to the crossover movement pattern. The adductors (inner thigh) assist in the crossover motion, while the core and spinal erectors work isometrically to stabilize the torso against the weight of the medicine ball.
