5-Minute Plank Challenge
Build a rock-solid core and hold a five-minute plank, growing your time a little each day with an adaptive plan and a cohort.
The 5-Minute Plank Challenge grows your hold from whatever you can manage today — maybe 20 seconds, maybe a minute — up to a steady five-minute plank. A short calibration hold sets your starting point, and PeakStreak paces the climb so every day is hard but doable.
Why it works
The plank is an isometric hold, so progress is measured in seconds, not reps — which makes it perfect for daily, low-impact training. Adding a small amount of time each session builds deep core and shoulder endurance while teaching your whole body to stay braced. Because there’s no jumping or load, you can train it nearly every day and recover fast.
What a day looks like
Each day shows your target time. You start the built-in timer, hold, and PeakStreak logs the result automatically when the clock runs out. The next day’s target adjusts to how the last hold actually felt — easing off after a tough one, pushing after an easy one.
Tips
- Squeeze glutes and brace your abs; don’t let your hips sag or pike.
- Breathe steadily — holding your breath ends planks early.
- Break a target into two shorter holds on hard days; the streak still counts.
Who it’s for
