Squat to press, one explosive chain.
Let the leg drive launch the press, don't squat and press as two separate moves.
The thruster welds a front squat to an overhead press with zero pause between them, so the quads generate the force and the dumbbells ride that momentum overhead. Glutes extend the hips to power the drive, and the shoulders catch the bells mid flight and steer them to lockout. Rep for rep it demands more from your body than almost anything else you can do with two dumbbells, which is why it anchors so many conditioning workouts.
The thruster is one continuous movement, the bells should be accelerating out of the squat straight into the press. If you stand up fully and then start pressing, you are doing two exercises and losing the point.
You are probably killing the leg drive at the top and pressing from a dead stop. Time the punch overhead so it rides the momentum of the stand, your legs should do most of the pressing.
Light enough to keep the rhythm crisp for every rep of the set. The move falls apart fast when the weight is wrong, and sloppy thrusters cost you everywhere at once.
