Rear Kick.

The ankle strap has had its day.

Cable kickbacks usually mean a strap that slips, one leg to balance on and a lower back that arches a little more with every rep, and then it is not the glutes deciding when the set ends. The chest and abdominal pad here holds the upper body firmly, so you can extend the hip against the load without something else giving way first. One leg at a time, with a clear contraction at the top. Olympic plates (Ø50 mm), 90 kg dead weight and 1525 × 1225 mm floor space. No strap. No arch. Just hip.
