The plank has a fearsome reputation it doesn't deserve. Yes, it's the most honest core exercise there is — no reps to count, just you and the clock — but nobody said the clock has to start at two minutes.
These five beginner plank variations build a stronger core from the ground up: two holds and three gentle moving planks. Twenty seconds at a time, plenty of rest, and a video of me demonstrating every one right here on the page. No crunches, no sit-ups, no neck strain.
Why planks? Because a strong core's real job is to hold you steady — and that's exactly what a plank trains. Better posture, a happier lower back, and more confidence in everything else you do.
How to use this workout
Quality beats duration every single time. Ten seconds of a straight, braced plank does more for you than a minute of a saggy one. If your hips start to drop, rest early — that's good judgement, not giving up. Dropping to your knees for any of these is the right version, not a lesser one.
The workout
How it should feel — and when to make it harder
Your middle should feel switched on and worked, your shoulders warm, your breathing steady. A trembling belly is normal — that's the muscles learning. Sharp pain, especially in the lower back, means stop and check your position against the video. When two rounds of 20 seconds feel comfortable, build to 30 seconds before adding anything new. And if you've got a health condition or you're on medication, a quick word with your GP first costs nothing.
Planks pair brilliantly with the gentler floor moves in my 10-minute beginner core workout — alternate the two through the week and you've got a proper little routine.
Quick questions
How long should a beginner hold a plank?
Twenty seconds with good form is a genuinely solid start. Build up gradually — 30, then 45. Long planks are a party trick; steady, well-held short ones are where the progress lives.
Are planks safe for my back?
Done well, planks are one of the kindest core exercises for your back — they train it to stay still, not to bend. The key is keeping that straight line from head to heels. If your lower back aches during a plank, your hips have likely sagged: rest, reset, shorten the hold.
Should I do planks every day?
You can, but you don't need to. Two or three sessions a week with rest days between does the job — your muscles get stronger while you recover, not while you shake.
