Movement basics
Carrying a light weight in each hand is straightforward only when the route, grip and set-down are organised before you start walking.

Use a short, level path with a non-slip surface and clear space at both ends. Avoid stairs, door thresholds, busy walkways and a route that requires sharp turns between machines. Walk it without weights first. If you have to squeeze past somebody or step over an object, choose another area.
Select two manageable weights with secure handles and enough clearance from your legs. You should be able to pick them up and set them down deliberately. This is not the time to test the heaviest pair you can lift momentarily. An instructor can demonstrate the pickup if it is unfamiliar.
Stand comfortably upright with the weights beside you, then take controlled steps. Keep looking along the route rather than down at the weights throughout. Avoid holding the shoulders in an exaggerated shrug or leaning backwards to counter the load. Breathe normally.
If the dumbbells swing into your legs or your grip begins to open, finish the carry and set them down carefully. Do not accelerate to reach the end before the grip fails. A shorter distance or lighter load is a sensible adjustment. The route is a maximum available space, not an obligation to complete it regardless of control.
For an initial practice, stop and put the weights down before turning to face the other direction. That removes the need to pivot while carrying. Make sure the set-down area is clear of feet, bottles and anything fragile, and avoid dropping the weights to signal that you have finished.
A carry becomes different when you change the distance, weight or pace. Note enough detail to repeat the version, such as a short marked route with a particular pair of dumbbells. Keep most variables familiar when making a change so the result is easy to interpret.
Carrying can be demanding even when the weights look small. Stop for pain, dizziness or unusual symptoms, and ask for advice if the task's suitability is uncertain. You can practise the walking and handling with a modest load without turning it into a grip endurance contest.
