Free plank timer for core workouts. Track your plank hold time and beat your personal best. Works for forearm plank, side plank, and push-up position.
Beginners should aim for 20–30 seconds with good form. Three sets with 90-second rests. Quality matters more than duration — if your hips sag or you hold your breath, stop and rest. Build to 60 seconds per set over 3–4 weeks before progressing further.
Intermediate: 60–90 seconds per set, 3–4 sets. Advanced: 2–3 minutes with strict form. Research suggests holding planks past 2 minutes doesn't provide much additional core benefit; instead, add challenge by using unstable surfaces or adding movement.
3–4 times per week is ideal. Core muscles recover faster than large muscle groups (24–48 hours). A daily plank challenge is possible but reduce duration on consecutive days. Always allow one full rest day per week for recovery.
Both engage the core, but differently. Forearm planks reduce shoulder demand and allow longer holds. High planks (push-up position) build more shoulder and wrist strength. Alternate between them: use the plank timer for 60 seconds each to get both benefits.
Use the 10% weekly rule: add no more than 10% time per week. If you hold 60 seconds today, target 66 seconds next week. This prevents burnout and injury. Track your personal best each session — even a 5-second improvement is progress.
