Practice mechanics of one-arm swing, and then switch arms at the same height/ timing in each rep (just under eye level, while weightless).
Weight does not change mechanics or expectation; Heavy or light- violent, standardized movement throughout. If you want it to be heavy, address it like it is.
Kettlebell swing reminder: If we lose our strong hinge, back rounds, or legs fail to snap straight in the “drive” portion of the movement, adjust accordingly and continue safely.
