30 Day Plank Challenge
Thirty days of core work that starts short and gets progressively harder, with six difficulty levels, scheduled rest days and a timer that runs itself.
Holding a plank while watching a timer is miserable
Counting down your own hold makes every second longer. The app times each interval and tells you out loud when to switch, so you can put the phone on the floor and concentrate on not sagging.
- 30 days of plank workouts already programmed
- Six difficulty levels
- Rest days built into the schedule
- Demo video for every variation
- Audio prompts so you can hold position without watching a clock
- Works offline

It gets harder on purpose
Week one is comfortable. That is the design: the hold times and variations increase steadily so that day 30 asks something of you that day 1 could not have. Six difficulty levels mean the same thirty-day shape works whether you are starting from nothing or already hold two minutes.

Rest days matter here too
Core work is still work. The rest days in the schedule are what let the hold times keep climbing rather than plateauing in week two.
