Floor to shoulders in one explosive snap.

Power comes from the hip snap, not the arms. Keep the bells close as they rise.
The power comes from a violent hip snap, which means the hamstrings and glutes load in the dip and fire hard to send both dumbbells from your sides to your shoulders. Keeping the bells close and dropping under to catch them trains timing and full-body coordination on top of raw posterior chain power. It is the natural entry point into explosive lifting for anyone without a barbell or the patience for one.
The bells travel at your sides instead of in front of your shins, so there is no bar path to manage and the catch lands on your shoulders rather than a front rack. It is far quicker to learn and easier on wrist mobility, at the cost of total load.
You are curling the weight up instead of snapping it. The arms should stay loose until the hips finish, then guide the bells into the catch. If your biceps are pumped after a set, go lighter and rebuild the hip drive.
Soft and quick. Punch the elbows forward, let the dumbbells land on the meat of your shoulders, and absorb slightly through the knees. Crashing the bells onto your collarbones means you are catching late or too upright.
