This is a great squat variation that one can supplement into their workout.
The asymmetrical load will challenge your trunk and hip musculature to prevent unwanted rotational and lateral movement.
Here are some squat guidelines that will be helpful.
Start the squat by pushing your knees apart while pulling yourself down with your hip flexors. Keep the lower spine straight and the abdomen pressurized when ascending. You want your squat to look like you have an equal load on both sides.
We prefer a kettlebell for this movement because it creates a better connection between the hand, arm, and body. Dumbbells are bigger and more cumbersome but can be used if a kettlebell is not available.
