Walk slowly holding a weight in one hand. Stay tall and don't let your body lean toward the weight. This trains your deep core to keep you steady.
How to do it
Hold a dumbbell, kettlebell or water bottle in one hand by your side. Stand tall with shoulders level and ribs stacked over your hips. Walk slowly in a straight line, breathing steadily. Switch hands and repeat.
Focus cues
Shoulders level. Ribs down. No leaning. Keep breathing.
Make it easier
Use a lighter weight or take fewer steps.
