With the crack of dawn, somewhere, a gardener trudges into their garden. They squat down on the garden bed and start digging the soil with a shovel. For them, it’s as harmless as a cup of morning tea.
I can't promise you won't break a sweat, especially in hot, humid climates, but "no dig" gardening is much easier than dragging out the shovel to turn the soil and get your garden ready for planting.
