The one cue
Ribs to hips. Breathe out hard at the top.
The same cue Kynetix shows on this lift during a workout.
How to progress
Add reps first: when you can do 15 clean reps on every set, make it harder. Slow the lowering to three seconds, pause at the hardest point, or add load with a backpack, dip belt or vest. Kynetix logs bodyweight sets with any extra load, so the progress still shows.
How Kynetix tracks it
- Log each set in a tap with weight and rep steppers. Your last set sits right there.
- The rest timer starts on its own after every set.
- Personal records are spotted as you lift, using an estimated one-rep max (weight x (1 + reps / 30)).
- Kyno suggests the next weight from your own history.
