Short Planks, Stronger Core: The 10-Second Rule You Need

New guidance suggests longer plank holds don’t boost core strength or reduce back pain. Emphasize short, high-quality holds (about 10 seconds) with proper form and brief rests in 3–6 rounds, or use a personal baseline up to 40–60 seconds with gradual increases and safer progressions. Practice 3–4 times weekly; avoid fatigue-driven form breakdown that shifts load to the spine and joints. Progression should come from variations, not longer holds.
