Is a 5-minute plank better than walking 10,000 steps?

I'm not good at planks.

But even doing it for a short while really does consume a lot of energy.

It's so hot these days, and instead of walking 10,000 steps, even just doing a 5-minute plank...

I was wondering if it might have an exercise effect comparable to 10,000 steps.

But 5 minutes is too short, right? ^^;;;

I think I'll have to do this for about 10 minutes...

Shall we try giving it a try starting today, even if it's just for a short while?

I do think that might help with core strengthening as well, though.

It's hot, so I keep thinking about efficient workouts.
